91 firebird TPI engine harness in a 91 Z28.

Hey posting here to see if anyone has any experience adapting a firebird engine harness to a Camaro.

I understand that the batteries on the other side and I can't figure out how that becomes a problem for hooking up any part of this harness.

I'm sure there's something that would need to be extended potentially but I can't see that being a huge problem.

If anyone has any experience here please let me know.

Thanks

Re: 91 firebird TPI engine harness in a 91 Z28.

If BOTH cars are TPI :

Fairly certain that the conflicts your going to run into are related to the HEADLIGHT harness. The Firebird Headlight Harness that connects to C100 is going to have the Firebird pop-up headlight wiring that is not needed for the Camaro.

TBI cars used a different electric Speedo wiring configuration ( buffer compared to the ECM ) so if dealing with a TBI harness that will need to be accounted for.

You can visit this page to get all the C100 and C207 information for the 91 Camaro and the 92 Firebird you will need to look over to be sure. https://berlinetta.info/tech.htm
