Thanks so much for all the detailed instructions. This has been a project for me for the last couple weekends.
I finally got to the finish line, but ran into some issues I really hope you can help with. First off, I have a 2001 TJ Sport that had no hardtop wiring. I completed all the setup just as you described except for I soldered the wires in the rear tub rather than dropping the fuel tank and such.
Unfortunately, it doesn't seem to have worked as I expected. My reverse lights and turn signals are not working.
I have a 98 top, with a 2002 tub harness. I did notice that it has an extra plug where the rear twilight wiring is:

I didn't use it because it was non-existent in my current 2001 TJ.
Do you have any idea if this is my problem? Seems I shouldn't have assumed it wasn't necessary - it does say RT LT for right turn and left turn...
Please help!
