Where do each of these wires go?

DON'T CUT THE RED WIRE!! :eek: you need the factory wiring diagram before you go any further.

THIS. I doubt Francis covers the IGN2 circuit from the ignition switch. The 73 book MAY be the same. You can download it from MyMopar. DO NOT go by the entire diagram, there are differences 73--75. I'm referring to the ignition switch diagram
