CAVEAT. BE VERY CAREFUL OF THESE CONNECTOR DIAGRAMS. Is this diagram looking at the FRONT of the harness connector, or at the PC board, which would be the REAR of the harness connnector? (Mirror views!!)
Edit. You are welcome. You need to follow this with every circuit, because of how they are drawn
EASE:
One thing I do is cheat. I refer to the 72 manual, which IS DIFFERENT but close enough that you can at least follow most of the wiring, as it is the last year, drawn the "line drawing" method. Also download the 2 page MyMopar af termarket diagrams. These are not as detailed, leave out options and some connectors, BUT ARE easier to follow.
Also, others suggest various 3rd party diagrams. If you are not comfortable with electrics, that would likely be a good thing to look into
