Hello everybody,
now that the different lamp shapes on the Pad have been clarified and I know how to scratch them, I wanted more clarity about the wiring of the many LED lamp circles with the power supply of my planned Diorama (1/160, 160 cm x 90 cm).
And my diorama could look something like this Mini-Diorama (1/700) by Tomytec, whose base plate is only 35 cm x 29 cm "big", but had a moon price of 682,30 €, but has been sold out since then.
Source: Andromeda24.de
At first I had only planned a fixed arrangement/wiring of all pad structures/components in the starting position for the Dio, i.e. with the MLP with the Shuttle stack on the 6 Pedestals next to the tower, as well as with the Crawler on its way before it.
The concept for the power supply for lighting the entire diorama was developed a few years ago in a close exchange with my Raumcon friend Arno (McPhönix), in which the Multi-Currentbank is the central component, which is designed for approx. 60 constant current circuits each with up to 8 LEDs, with which all lamp circuits of the Launch pad (FSS/RSS/Service facilities/spotlights) as well as the [color=blue ]MLP[/color] and the Crawler are powered.
This original concept has in the meantime been revised and modified with regard to more location flexibility or Mobility of MLP and Crawler so that not only this one arrangement is possible with the MLP standing in front of the tower, but also during the MLP approach to the pad, like in this photo during the Challenger rollout (December 8th, 1982) in the fog.

Likewise the cabling between the diorama and the power bank has also been modified so that it can be separated if necessary.
In this context, I initially had a detachable cable connection on the MLP via a small plug-in connector on the underbody next to the Pedestal 3, which I have now moved to the other side and planned for the Pedestal 6 besides the tower, since the whole cabling of the FSS/RSS is also planned on this side and all cables/wires can be led down together to the pad bottom.
In order to be able to implement this mobile location concept, we have meanwhile also agreed to install our own power supply (three 9 V batteries) in the Crawler, on what also the MLP can be connected by means of a plug connection if it is in a pulled-out position on it.
Consequently, a suitable location had to be found for an interface between the power bank and the pad cabling, which is shown in this drawing with the connection plate,
Source: McPhönix
whereby NASA befriended us with the construction of the pad infrastructure with a small building, as will be shown later.
In order to get a better overview of the local conditions on the Diorama as well as an idea of the size of the space available for the wiring of the pad assemblies, I picked out my former Dio draft, what for I've used an older one Google Maps image (2012) on which was seen the Launch Pad 39A in its original form with FSS/RSS,
in which I have drawn the floor plan for the diorama in the Scale 1:160 (1600 mm x 900 mm) and marked the MLP and the crawler.
Then I've drawn the Dio to scale on paper and put on placeholders for the MLP and the crawler, for which I had to roll up the carpet in the study. And while I kept checking the dimensions on the PC in between, Gino had made himself comfortable at the end of the Flame Trench and began falling asleep ...
And since it was already late or early again, we've went to sleep together ...
And with that, good night ...

Hello friends,
and now it goes from the 2D view into the 3rd dimension, for which I've placed the FSS and RSS of my deceased Raumcon friend Thomas Emberger († 2017) onto the diorama floor plan, which I took over after his death from his wife as his legacy in order to keep an honorable memory of him on my diorama. May he rest in peace ...
Then I also added my MLP, which rounds out the picture further.
But as a precaution I quickly put the MLP away and parked it in the closet.
And with that back to the wiring on the Dio plate, which I imagined as follows.
The planned interface for the possible decoupling of the MLP has been modified and is now laying on the Pad ground besides Pedestal 6 and takes place via a small Connector (Plug with socket).
The LED Lamp circles on the FSS and RSS will all be laid downwards on the back of the FSS, especially because there are already lots of pipes etc. there, so that the LED wire bundles will be hardly noticeable.
Fortunately, there are also two cable ducts at this point, which I will use of course,
in order to lead the LED wires to this small building, which was built there that time thanks to the wise foresight of NASA!
This concrete structure with blast doors, housed the freight elevator (on the left) and the door to the stairwell (on the right) which took you down to the Pad Terminal Connection Room (PTCR) at ground level, with further access from there to the roadways and parking areas scattered around the pad, as James MacLaren explained to me yesterday.
And in this building at the back of the diorama, the already shown Connection plate can be conveniently accommodated, which is why I've measured out and scaled it right away,
from which all cables are then be led to the Current bank, which also has a plug connection.
As far as the wiring of the MLP is concerned, the three lamp circles as well as an additional circle for Caution lights are still easily manageable. And for the Crawler Transporter it will certainly be similar, although I still have to do the exact lamp analysis. That should become difficult again, however, since there are only a few images of the MLP-2 Crawler, used during STS-6, let alone still with lighting.
But more on that soon.

Hello everybody,
during my search for suitable ways to wire the LED lamps, I've already looked extensively around some nasatech.net Street View panoramas of the Launch Pad 39A.
And since I was there once, I has been going on with further structuring my diorama floor plan, which goes beyond the immediate launch pad area.
The entire Launch Complex 39A (LC 39A) has an octagonal configuration and covers around 160 hectares of land.
Source: NASA
Due to the associated facet-like arrangement of the huge concrete retaining walls (18°) rising at an angle to the launch pad, which can be seen in this photo,
Source: NASA
extensive measurements of the contours and distances including the conversion of the dimensions to 1:160 were necessary, which was quite laborious and time-consuming.
For such measurements, however, one needs the most exact reference dimensions possible, which can be used as a basis, for which even the scales in Google Maps are only partially suitable, as I have found.
Therefore as a reference dimension I have chosen the width of the Flame Trench given in NASA Facts Online of 58 ft = 17,68 m ≙ 111 mm (1:160) and have drawn the contours calculated with it in my Dio floor plan.
In this image one can see how close the MLP on the Crawler is standing next to the tower.
Then I've started to deal with the SSWS inlet pipes in the back corner of the diorama (red frame),
which are connected with an elevated water tank standing on a tower, which has a capacity of 300.000 gallons (1.135.620 liters) and a height of 290 ft = 88 m ≙ 550 mm (1:160).
Source: capcomespace.net
Then I've tried to print out a copy of this place with the bizarre pipe system that was as true to scale as possible in order to stick it onto the Dio floor plan, which is problematic without precise knowledge of the pipe diameters.
However, the copy ends right in front of the tower, which was clear to me from the start when planning, but now it didn't want to like to me regarding the perception because it would certainly look somehow strange.
But since the water tower is a striking detail next to the launch pad and should therefore not be missing on the diorama, I've decided to add a small extension at this point of the Dio, on which the water tower also has space, which certainly rounds off the overall picture, which Gino does not seem to be very impressed with.
Before determining the dimensions of the water tank I have to get an exact reference dimension, because I only know the height of the tower (290 ft ≙ 550 mm (1: 160), and that the water flows through pipes with a diameter of 2,1 m to the pad. 
Source: NASA
And to determine the tank diameter or other diameters from a height is unfortunately too error-prone, as I have already found elsewhere.
So I have to do some more research to be sure.

Let's get on with it!
As it is said in a Bible verse, "He who seeks finds".
And so I've actually made a find in my extensive SSWS collection. It doesn't always have to be brilliant HiRes. reference photos, but rather as in this case the following schematic representation of this branched pipe system at the foot of the water tower, from which the different pipe diameters are to be seen, of which the diameter 114" = 2,9 m ≙ Ø 18 mm (1:160) can be used as a reference dimension for drawing of the water tank, which I've also done then. 
Source: capcomespace.net
In addition, the clear display shows which SSWS systems in the Flame Trench and the MLP are served with water by the two 84'' pipes. These are the said pipes with a diameter 2,1 m ≙ Ø 13 mm (1:160), which one can see very nicely in this Street View panorama, as well as the changing diameter of the pipes following to the tower.
Source: google.com/maps
And with this diameter (114'' ≙ Ø 18 mm (1:160) as a reference dimension, I was able to determine the different diameters of the water tank (blue) that I need for scratching.
Source: NASA
The required heights I've determined from this photo, in which I used the height of the tower as a reference measure.
Source: NASA
When drawing the top view of the water tank for the diorama, one must note that the tank stands on a support structure consisting of five steel pipes that has a pentagonal floor plan, which is why I also had to deal with the designing a Pentagon , which is by no means trivial, but fortunately there are instructions for this.
In this image some details are drawn in that will be taken into account later when scratching. At the rear support tube there is a ladder with a protective cage , which leads up to the railing on the top of the water tank,
which I've only recently recognized on closer inspection in this image.
Source: google.com/maps
On the pipe distribution system there are also 13 lamps, which would certainly also be attractive to scratch, which one can see on this panorama. 
Source: nasatech.net
And since we are back to the lighting, here is a picture in which the foundations of the four Floodlight masts of the pad lighting are glued on.

But that's supposed to have been for the present with the Diorama plan, especially since the Dio will sound the bell for the Final countdown of my project, which is still a long way away ...

Hello everybody,
to err is human, said the hedgehog, getting off the brush ...
If in doubt, I always ask James MacLaren, and so this time too, whether he also had been once at the Water tank tower and has seen a Ladder with protective cage as I has suspected it.
And lo and behold, he was actually there once and says, that the ladder there probably had no protective cage according to his memory. Accordingly, there were ladders with protective cages on the Launch pad, such as also at both corners of the MLP (Side 1), as well as without, wherefore there were apparently no uniform regulations.
In the case of longer ladders, the pad climbers were secured using a safety wire rope with fall protection, as is also used by mountaineers.
The little house on top of the tank, which I also asked him about, was a screened enclosure to keep birds and bats out, and perhaps people too, especially since inside of it, the top of the tank has a large opening.
So far, so good, although from the point of view of German safety regulations I was surprised with the missing protective cage at this height.
By chance I also still found a confirmation that the ladder at the water tower actually has no protective cage, for which this GigaPan panorama has furnished evidence for, what I have saved in my optical memory, because it has an incredible resolution in the zoom.
Originally I wanted with the help of the perfect direct view and the known height of the High Pressure Gas Battery of 32 ft = 9,75 m ≙ 61 mm (1:160) only determine the height of the Launch pad area of the diorama.
On the occasion I also looked at the water tower and when I zoomed up I was amazed at the superb detail resolution, since one can now see what the ladder of the tower really looks like from the bottom until the roof of the house on top of the tank and up to the navigation light, and that it has no protective cage. 
Source: GigaPan
As one can see, a continuous strand/rod runs above the middle of the rungs over the entire length of the ladder, on which one can probably secure himself with a fall protection device.
Since the length of the Gas Battery, 110 ft = 33,5 m ≙ 210 mm (1:160), and its width, 56 ft = 17,1 m ≙ 107 mm (1:160), already have been drawn into the diorama plan,
I have drawn the height 32 ft = 9,8 m ≙ 61 mm (1:160) into this GigaPan section and determined the height from the Dio floor to the pad surface, which is approx. 76 mm and thus roughly corresponds to the depth of the Flame Trench, 42 ft = 12,8 m ≙ 80 mm (1:160).
And with that I would like to definitely conclude the planning phase of the diorama.

Hello everybody,
is there anybody in there?
I want to come back briefly to the Launch pad lighting once more, which I have assumed so far to consist of four Floodlight masts at the corners of the pad, but unfortunately the following photo does not show enough details.
Source: spacefacts.de
The foundations of the masts I had already glued into my Diorama plan.
To scratch these masts one needs more detailed photos, which one can also find indeed, such like these ones here, whereby I always have to consider their historical relevance.
Source: NASA
Source: NASA
This is what the masts looked like only in the second half of the shuttle program, while on photos of the first missions, like here during a so-called Flight Readiness Firing (FRF) during the preparations for the launch of the Challenger to her first mission (STS-6) one can see that the masts at that time were higher, but far more spartan and, in contrast to the later modernized main masts, had not 9 + 3, but only 6 Flood light lamps (4 above, 2 below).
Source: NASA
Fortunately, there are more precise images of the extensively documented STS-1 mission, as one can see here, on which one can even see the rungs on the mast for the pad climbers.
Source: NASA
These details look pretty good, but unfortunately they are not enough for scratching, since one has no clear reference measure to which one can refer all dimensions when converting.
So I've searched further and found this STS-1 photo here, on which one can now see important details that are crucial for scratching the floodlight masts, which one can see more clearly in the zoom.
Source: NASA
A first important finding from this is this one, that in addition to the four floodlight masts found so far, there is also a 5th Mast, which stands directly in front of the Gas battery bunker, is slightly lower than the other four masts and has only four flood lights.
Even more important, however, is the fact that with the height of the bunker of 32 ft ≙ 61 mm (1:160) I now also have a reliable reference measure with which I can determine the height of this mast (128 mm) as well as the dimensions of the spotlight holder.
Source: NASA
On the other hand, by using this mast height as a reference measure I was able to determine now also the height of the four longer main masts via the Mast 1, which is 144 mm.
One can also see that there are lamps on all ceilings of the Bunker cells, which means that another LED circuit is required, but what has already been considered by my friend Arno (McPhönix) as a reserve in his Multi-power bank.
And as optical details one can see in this photo that the large gas containers in contrast to the shown GigaPan-Panorama had a gray paintwork during the first missions in the early 80s, and that there was no container in the 3rd cell (behind the mast), what is explained by the fact that the GigaPan-Panorama shows the Discovery before her last launch for the STS-133 (2011).
As one can see on this panorama, this mast (red) was modified in the following years and afterwards only had two smaller Flood lamps. But there is a further Floodlight mast (yellow) on the Gas battery with 9 Flood lights, which one can see better in the following nasatech.net panorama, but what doesn't interest me any further, as it didn't exist yet 1983.
What interests me, however, is the position of the base point of this mast in front of the battery in order to be able to decide whether it is still on my diorama floor plan or not.
Source: nasatech.net
And after I took another look at my first photo from the STS-6 Rollout, one can also recognize this 5th Mast that was already existing there back then exactly at the same place,
so that I could also determine its base point. And that is situated indeed on the front edge of my Dio, so that I can now also consider this mast in my pad lighting, provided my friend also has considered a Floodlight LED-Circuit for it in reserve too.
And finally, one more thing that I was very surprised about at first, because on a Google Map (2012) the mast, which was still visible at this point in the GigaPan panorama (2011), one year after the last shuttle mission (STS-135) was already no longer there, as one can see here.
The final proof of this is provided by this nasatech.net panorama, which was updated lastly after the end of the shuttle program, on which only the foundation of the mast with cut cables can still be seen at this point ...
Source: NASA
With this impressions I can for now finally roll in my Diorama plan and instead roll out the carpet that my Gino likes to lie on.

Hello friends,
since my Multi-power bank still has a floodlight LED circuit in reserve, I've swarmed out again and actually still have found a 6th Mast on the pad, at this already known location next to the building, about its purpose I had reported in Reply #1941 about which, according to James MacLaren, one could get by elevator or stairwell to the Pad Terminal Connection Room on the ground floor.
Source: Google Maps - Street View
And next to the building there is actually a Floodlight mast, which illuminates the FSS/RSS rear, wherewith the 6th Mast of the Pad lighting would be found, which can still be fed by the power bank.
The crucial question is only whether this mast was already there during STS-6, which I suspect. And that's why I will now look for photos from this time that provide information about whether the mast come into question for my Diorama or not.

Hello everybody,
since I now know which point on the pad to pay attention to, I've first viewed my STS-6 photos, and already on this photo from the Rollout, on which one can see the back of the pad behind the RSS, one can actually see the contours of a further Mast (6) at this point, albeit blurred, next to the building in question.

More accurate information about this 6th Floodlight mast then again gave photos of the STS-1 like this one, on which in the zoom one can clearly see the illuminated mast behind the building,

Therewith the available 6 Floodlight LED circuits of the power bank are now exhausted, so that I don't need to look any further.

Thanks Dave for your sustained interest and enthusiasm.
BTW, it was a similar situation for me in the beginning, when all I wanted to do was building a Shuttle stack, until I saw a friend's project who built the Revell Launch Tower Kit.
This complex project fascinated me more and more and ultimately inspired me to do the same, which taught me a lot about this ingenious space technology. And so I started and had also dreamed of a Diorama even then, and I have held on tight to this dream to this day, where it has now become a concrete plan.

Hello everybody,
after we have meanwhile decided a separate power supply for the Crawler lighting by means of three built-in 9V Batteries, the analysis and inventory of the lamps located on the crawler is now the next step for the definition of the corresponding LED switching circuits, which, however, should become a bit difficult, since there are almost no photos from the STS-6 in which one can see the illuminated crawler.
Only on this photo during Challenger's rollout (11/30/1982) from the VAB one can see the crawler, on the front of which (Side 1) one can see 8 lamps, at least something! 
Source: forum.nasaspaceflight.com (jacqmans)
Of this rollout there is also the following Video, on which unfortunately a lot was disappearing in the fog ...
Therin in a few short sequences, like this one, one can make out a few lamps, but the position of which can only be guessed.
Photos from later missions, like here from the STS-132,
Source: live.staticflickr.com (Ben Cooper)
or here from Endeavour's rollout to her last mission STS-134 are helpful, but there are a number of lamps there which were not yet present on the crawler during STS-6, which must be taken into account when taking stock of the lamps.
Source: live.staticflickr.com (Ben Cooper)
Therefore, I firstly had to orientate myself on images from subsequent missions, such as this one during the Challenger rollout, STS-8 (30/08/1983), on which one can see the back (Side 3) of the crawler.
Source: forum.nasaspaceflight.com
This photo of the STS-28 (1989) is quite suitable for the analysis, on which one can even see some lamps on the inner sides of the Trucks.
Source: flickr.com/photos/nasacommons
The difficulty with the inventory is now to disregard those lamps in the counting that did not yet exist during STS-6, such as these ones during STS-134.
These are Fluorescent tubes, which are located immediately in front of and behind each of the 8 Trucks, which are mounted at elongated Lubrication Jigs for lubricating of the truck chains, as one can see in this image.
Source: NASA
As one can see in this image during the STS-28, these lubrication jigs were already present on the STS-6 Crawler, but the fluorescent tubes weren't still there, because they were just retrofitted later.
The exact inventory of the lamps will follow in the next step.

My dear friend, No worries!
I have my own power station which is my mighty Multi-Current-Bank by my friend Arno (McPhönix).
After my extensive analysis in Reply #497 I had planned about 330 lamps, whereby the Diorama is not yet completely included, which means that the number will still increase a little.

Hello everybody,
and so now to the result of the analysis and the final inventory control of the Crawler lighting, which is now fixed and can be seen in the following image, which however does not show the STS-6 Crawler, but the Crawler CT-2 that was upgraded for the SLS Program.
Source: NASA
The total 29 Lamps of the former STS-6 Crawler are distributed as follows:
Driver's cabs: 2
JEL-Hydraulics: 8
Trucks (out-/inside): 8
Sidewalls: 2/2 Beacons
Front side (Side 3): 3
Back side: (Side 1): 4
And this result actually corresponds to my initial estimate of approx. 30 Lamps.
Just briefly to the explanation of the NASA designation of the front and back side of the Crawler, which was incorrectly named in my last post.
The crawler with the MLP drives from the VAB with the Side 3 (front side) in the direction of the Launch pad. Therefore from the south side on the pad one always looks at the Side 1 (back side) of the crawler, which then becomes the front side when it return.
Source: flickr.com/photos/nasacommons
The Side 1 of the crawler one can recognize, in difference to the Side 3, by the the stairs platform onto which the MLP stairs can be folded out, which is folded in again after the MLP has been set down onto the Pedestals, before the Crawler returns.

Hello everybody,
now it's time to get in touch again.
After the analysis and inventory of the lamps on the crawler, I've thought with my friend Arno (McPhönix) behind the scenes about the placement of the electrics for the Crawler and MLP lighting.
And to do this, I first had to familiarize myself more closely with David Maier's Paper Kit and take a closer look at the structure of the crawler, which is based on a fixed substructure in a similar way like the structure of the MLP that time, long, long ago ...
Here one can see the floor plan for the construction of the Crawler support structure and underneath the corresponding principle sketch,
as well as my first idea for the placement of the three planned 9V Batteries.
It can be seen from this that some of the support elements planned would have to be dispensed with in order to create the necessary free space for the batteries.
Source: EDU-Craft Diversions (David Maier)
In principle, however, this should be feasible because in D. Maier's kit, in contrast to the ingenious Paper Kit (1/96) by Mischa Klement (www.microartwork.com), no internal spaces are provided, which is the construction much simpler and easier.
For comparison, here is a picture from the building report of a US friend in the Paper Modelers Forum (gene1772), who built this monster crawler out of around 11.000 parts.
Source: papermodelers.com/forum (gene1772)
And here his masterpiece can be seen in all its beauty.
Source: papermodelers.com/forum (gene1772)
A great help in further building the crawler is the building report of my friend Michael Knobloch (mk310149), who also built the crawler from the Maier-Paper Kit (1/144), is, exactly as it is provided in the kit, the pictures of which I will refer back to from time to time.
After some consideration, we came to this arrangement of the Electrics/Electronics, which is more favorable in terms of the division of the elements, for what the support walls (green) were modified.
In the meantime, my friend Arno has tinkered on the electronics and specified the circuit board, in which even a warning horn is provided.
Now I just have to find a convenient place for the exit of the connection cable to the MLP when the Crawler with the MLP is standing in front of the Flame Trench and its power supply is through the batteries of the crawler.
And now still a brief outlook ahead to the building of the Crawler, in which I will proceed similarly to the construction of the MLP and will scratch certain details, which David Maier has left out in his kit or only hinted at it through clever textures.
This concerns, among other things the Underbody of the crawler, on which the lower support structure is only indicated, as one can see here, onto which equipment such as tanks, silencers, filters etc., as well as the exhaust system are simply placed then.
Okay, now one could say that one can't see the sub-floor anyway, and there are certainly more interesting places on the crawler, but on the other hand, the support structure could be represented relatively easily using suitable profiles.
Source: papermodelers.com/forum (mk310149)
Instead, other places on the crawler such as the JEL Hydraulic system for lifting and lowering the MLP on the Pedestals are much more distinctive, but also much more difficult for implementation.
Source: NASA
And this tricky assembly is indicated in a typical way in David Maier's paper kit only by relatively robust structures with 2D textures, which may look pretty good when viewed from a distance, but up close one can see that this is only printed "wallpaper" is as one can see in this picture. 
Source: papermodelers.com/forum (mk310149)
Then there are also some places with breakthroughs where there are provided only black areas in the kit, as one can see here. Strange is also that for the sake of simplicity, black color is provided in the interior in the front and rear open spaces, so that one cannot look into it. 
Nothing against the Crawler and the other great paper models of my friend Michael Knobloch, who is a passionate paper modeler and a master of the nimble scissors, who is cherishing his hobby above all else.
Source: papermodelers.com/forum (mk310149)
Ultimately, in addition to the question of the effort one wants to make, it is all a matter of taste, about which everyone can judge differently, according to his taste.
So much for today my friends.

Hello dear friends,
actually I wanted to leave it at the result of my previous inventory of the Crawler lighting.
But at one point I'm starting brooding again and again, so that I can't stop thinking about it, which is why I took a closer look at it once again. 
It is a matter of this area at the underbody of the crawler, on which one can still see some circled lamps on/in front of the inside of the Trucks, which have not (yet) been taken into account in my previous count, the exact position of which is difficult to make out on my reference photo of the STS-28 (1989).

Since two of these lamps have already got my attention in the video of the STS-6 Rollout,
I've already done some more thorough research and actually found what I was looking for, namely at my friend Mischa Klement, whom I has inquired about the diameters of the crawler's tubular support struts.
On his homepage one can find under Support a very detailed and nicely illustrated construction manual, in which I, among other things, also came across this image, which immediately made my heart beat faster because there the construction is shown at this point, where the lamp can be seen in the video (circled in red).

This is one of the two attachment points between which the Longitudinal Steering Cylinders of the truck steering are mounted, on the center of which there is also a lamp, as one can see in the following both images.

And those are the three lamps that one can see here again on the Crawler (Corner B), wherewith this last question would also be clarified.
This results in the following modified Crawler lighting, which contains 40 Lamps + 2 Beacons,
which are distributed onto the following 6 LED Circles:
Corner A to D: each 7 = 28
Side 1/Side 3: each 6 = 12
How good that my friend Arno (McPhönix) in wise foresight has again planned in his Electronics 6 circles with each 7 LEDs.

Hello my friends,
today is a very special day for me, but probably nobody can figure out what might be, or can you?

Manfred,
I am thinking today was your first "like" by no other than "Starbase101".
Ed: (and let timezones be damned).
