reverse lights

Easy to check. Find the 4 wire connector coming out of the firewall on the drivers side. THere should be two wires one color and the other two wires both another color. Two are the ign - red w/? stripe and the other two will be black w/red stripe. Pull the connector apart and jumper the two black w/red strip wires on the firewall connector. Turn the switch on and the back up lights should be on. Troubleshoot from there. If no lights, pull the jumper wire and make sure you have 12v, or a good test light indication on one of the two terminals that you had jumpered. If that's good, hook your jumper back up, and check connections in the trunk. Especuilly grounds, AND the bulbs in the backup light sockets. If no 12v, check the fuse box. I didn't dig up the exact fuse. Busy today. Also watch for rust on the contacts of the fuses, and watch for ancient fuses that look good, but the end caps have disintegrated inside and come loose.

Oh yea, there is a connector for the back up lights above the drivers kick panel too. Where it makes the run to the trunk.

Do what I did, Take them off. I believe that not all 66's came with them, Correct?? I wanted to clean up the rear of the car and replaced my rear valance with one that did not have the reverse light holes. I also welded the the valance in for the smooth look.
