I am looking for a good cond engine wire harness for a carbed 502 w/ the alternator on the starboard side. My eng has a single serpentine belt.

I used these. Made my own custom harnesses. It's the same one merc used. All colors are the same. You only have to add a couple wires involving alternator, starter, relay and 50 amp breaker.

You should have the relay and breaker on your mpi stuff. If not they aren't real expensive. Depending on age if the harness you can't see the corrosion down through all the wires. I debated re using but didn't wanna risk electrical gremlins. Lol. Good luck either way.
