1972 Cutlass S had coil/regulator/points distributor. Now HEI. Also switched to one wire alternator. New American Autowire engine harness has been changed to accommodate. All please express opinions as I may no longer follow stock diagram?

 

Is there a specific question? None of your mods are completely out of the ordinary.

 

Unsure which wires to attach at junction now that things have changed. I assume that talking to American Autowire representative would be the way to get my answers.

 

I would assume you should have schematics of the American Autowire harnesses or at least the deviations from stock.
