I've just got my camaro (68) togehter after a two year build. The car doesn't hold a charge and has not restarted after warming up and driving. I've changed the brand new starter, got a starter blanket. Now the horn relay heats up very quickly. I believe the horn is shorting out. The wiring diagram I have doesn't match the color wires that are connected to the relay? I'm not sure what goes where? (Red and Black to the prongs at the bottom of the relay and a green , pink with a blue stripe, and a pink wire.) They have plugs on the under side of the relay. Also after two or three short drives, my reverse lights won't work. New bulbs, and B&M shifter. The switch is plugged in and the wires look good. I'm not sure if this is all connected or not?
