I would start tracing all the main feeds. Both under the hood and under the dash. They are all 12 gauge, Red and pink for feeds, heater is run by a brown one, and the solenoid is purple.

Under dash harness is easier to trace by removing in one unit. You will most likely find that easier to remove by also removing the dash gauge cluster. From there tracing all the wires will be much easier.

Checking continuity and resistance is a good idea at this point. Most of the old contact points on the crimp connectors.

It is tedious, most guys get too frustrated and just buy a 4-6 hundred dollar replacement. I found 3 old harnesses for 80 bucks and used the good parts, wires from them.

Almost got mine running today, have to check my flywheel for out of round then shim the starter appropriately adding a starter brace.

Oh, and yea, my nerves are pretty cooked right now.
