I have a 68, all of the side marker lamps work just fine, but the rear lights don`t come on. also I am unsure where the 2 wires at the dash side of the rear harness hook up to. one wire is black the other is white and the have spade ends. on the front harness there is a single wire with a spade end I cant find where it goes either. It is on the left side right next to where the horn relay is.
