Ok so here goes. Got the wiring kit from Megaparts with the Violet wire and the black wire with the jumper for the light in the dash. I have (2) 68 Mopars (Charger and Runner) here I am trying to wire in the reverse lights. Both cars are missing the harness completely. Everyone is saying use port Z in the bulkhead for the wire to go to the reverse light on the dash as does the instructions included. I am working on the 68 Roadrunner at the moment. Both cars use port Z for the left hand front marker/turn signal light according to the Wiring diagram for 68 and the cars themselves. Dark Green wire with a white tracer. So that wont work to use that port for that light. Also, they want me to plug the two wires into ports C & D on the wiper bulkhead on the top plug, but looking into the inside of the car, there is nothing in there on those two plugs to get power from on either car. The only thing shown in the wiring diagram for 68 that goes into those is the auto tranny backup switch if its an auto, so what the hell is plugging it into that going to do for me for juice? This thing is driving me nuts. Why is the 68 so different from all the pics I am seeing of 69's and up? Am I missing something? Someone chime in if they can help solve the reasoning why its so different?
