I have looked on Lectric Limited and American Autowire websites but they do not list them. I have not phoned them yet.

I am looking for a new engine wiring harness for a 1973 Oldsmobile Cutlass with a 455 engine and air conditioning. This is the harness that has the hookups for voltage regulator, sending units, and alternator plus whatever else.
Has anyone ordered one?

 

That one's probably gonna be a custom job and a one-off. Is yours buggered beyond repair? Hint- if you're just replacing a 350 with a 455, engine wiring is the same.

 

Given the lack of popularity of the 73-77 cars, I'd be surprised if someone repros the harness.
