    O.K. here's the deal. My 1991 has never had reverse lights since I bought it 6 months ago. I crawled underneath, but everything looks like it's hooked up to the tranny like it's supposed to be. So, then (with all of your help) I found the switch on the steering column (under the dash) I turned the ignition 'on' , put the tranny in 'reverse' , then tried ratcheting that switch back and fourth, but still, no go.

    What should I do next? I do have an electrical test light, but I don't even know where to start. I guess my question is, "what is the common point of failure for this system?"

    Thanks, you guys (and gals) are great!

    Have you traced the wiring along the frame and back by where the harness goes through a small hole in the frame behind the bumper area? My harness was wore through from the frame rubbing on it. Maybe a wire was rub apart..

    Also, Did you check all your fuses??? :)

    My wiring diagram is for '81-'85, but should still be close. The dark blue(dk green) wire comes from the fuse box. It goes to one side of the switch. It should turn the test light on when the ignition comes on. Current should pass thru this switch, (test light on) when in reverse, and go to the back-up lights via the light green wire.
