I have an 87 Firebird. It had the 305 and I swapped in at 350. I’m trying to get rid of as many wires as I can as I went carbonated and I’m no longer using the computer. So here’s my question. The alternator that was in it was a four pin alternator and the connection only has three wires so I’m thinking one of the pins in the alternator may not get used. I got a good price on another alternator that is black powder coated and is only a two pin. how can I get the factory connector on the wiring harness to work with the newer style two pin alternator?

I have included pictures to help.

 

Search cs to si, can even buy an adapter harness. What’s a carbonated engine 😆

 

It’s an engine with a lot of bubbles. Especially when the owner meant to say carbureted lol

 

I thought it runs on Pepsi

 

It would be much cheaper than super unleaded
