I have a '66 GT Coupe. I've had the car forever but the backup lights have never worked. I put new bulbs in and nothing happened, so I thought I'd start checking wires to make sure everything was connected. All of the wires in the back seem to be ok, I can follow them just over the drivers side wheel well in the trunk (where do they go from there?). I found the switch on the C4 with four wires coming off of it. All four of them are wrapped in a ton of electrical tape and run up through the engine compartment. Two of them are used up front, but there are two that just hang there. Do these go to my lights? I tried reading the Haynes manual but got kinda confused. Any suggestions on where to start? It came from the factory with a 4sp but was swapped to a C4 by a PO (probably the same one that took the HIPO out ). The neutral safety thing seems to be ok because the car will only start in park and neutral. Thanks.
