Burnt some Spaghetti!

Knowing its a '73 Duster, I can give you a little head start. If I recall correctly, '73 shop manuals are the start of the more complicated wiring diagrams. Often the circuits have to be pieced together from several pages. Splices are shown as diamons instead of solid circles.
The circuit coding remains the same.
Circuit Name, wire segment, - wire gage, color code

Since the wires of interest are very close to the multiconnector, I think I would start there.
Look closely at the connector to see if there are letters next to each cavity. In the shop manual go to the connector section and I'm pretty sure '73 has a circuit list.

let me see what crib sheets I have made for folks here in the past.
