Those sound like the wires for the reverse switch. I replaced my reverse switch a couple of weeks ago. If I remember correctly, both wires are green, one with a either a black or a white stripe. Assuming that the contacts on the tail light boards are making proper electrical connection, and the fuse is good, testing should be simple. Turn the key to the on position, and jump the wires. The lights back up lights should come on. Once you connect the wires to the switch, the lights should turn on when you shift into reverse. In my case, I had a bad switch on the tranny. There was a little corrosion on the outside, but nothing really visable that would indicate an internal failure. Wheather the switch is good or not, there is a rubber boot that is supposed to cover the switch to keep it dry. It has a hole on the end for the wires to go thru. If you don't have this part, it would be a good idea to pick it up. -Robert vin 6585 "X" --- In dmcnews@xxxx, "Paul Salsbury" <paul.salsbury@xxxx> wrote: > Hi all > > Ok... so my reversing lamps don't work, and never have since I bought the car...
