As has already been noted by northanger, 195xxx tiles are located on the upper wing areas. The general location diagram has been posted in other threads on this forum, but since it is not in this one I have posted it again in for easy reference. Link to original file is www.aeronautics.nasa.gov/pdf/tile_placement_chart.pdf
I have not been able to find tile 195002-356 itself, but have found a couple of near misses on a fragment of an Atlantis tile map from a STS-132 DAT TPS (Damage Assessment Team, Thermal Protection System) presentation available on L2. Tiles 195002-350 and 195002-351 are located on the upper side of the port (left-hand) chine area - this is the part of the wing/fuselage structure that is forward of the Reinforced Carbon-Carbon (RCC) leading edges.
I've attached a copy of the relevant slide from the presentation with tiles 350 & 351 circled in yellow, and a close-up view of the map's 195002-xxx block (41 tiles). The main tile map shows the view when looking at the orbiter from the left-hand side, with the crew access hatch to the left and the beginning of the wing leading edge at the lower-right. (This slide is showing tiles that were missed during flight-day 2 TPS inspection using the orbiter boom.)
It's possible that the tile we're trying to locate is on the other side of the orbiter in a similar position. There are minor differences in tile IDs between orbiters, so another possibility is that it may belong to one of the other orbiters on the same side (I could only find a map for Atlantis). Either way, I think there's a good chance it is from that general area, left- or right-side upper chine.
