Another update for anyone who is adding cruise control to a late year 1HDT. I reviewed the wiring per my comment above and realized there are more than 2 pins that need to be changed to adapt the cruise control computer I had from a 1994 1FZFE. I kept looking at wiring and quickly figured out that the 1997 Land Cruiser and LX450 had a different computer compared to previous years. The wiring for this late computer was exactly how my harnesses were wired. I found a module for sale and purchased. No wiring modification required - just plugged it in and everything is now working. I did have to undo the few pins I changed in order to try and make the earlier module work.
08/1996 to 01/1998 - 88240-60170 -> this is the one I purchased and it worked as expected. Bolts in same way as other modules; onto the brake pedal.
11/1995 to 08/1996 - 88240-60060 -> not compatible with my late year 80 series.
Cruise control is active and my foot is off the pedal.
This is how it mounts.
