Thanks and good morning Hoppy...

The current harness has been butchered over the years. First modified by extending the distributor wires for the big block by dad, then the last owner had a bunch of scotch locks and other cobbleness done. I guess maybe I will look at it closer and see what can be done with it. I am missing a lot under the hood and new to these cars so it will take a ton of Google searches.

The YO harness I bought was almost as good as an original. So its time vs money situation.
Dont waste much time with g**gle.
Print the wiring diagrams. Then lay out your existing harness on a board with everything labeled.
Then look for pictures as you need, but nothing working from the real thing.
Mark up the diagrams as needed - add in the ECU harness.
Make your own harness diagram. Harness being how the wires are bundled and connect.
