I have a 92 rs that is tbi and im trying to put a 95 lt1. It came with a ecu for a 95, a new wiring harness, i think its a stand alone harness. Its alot different than the one that i took out of the rs. my ? is what do i have to do to connect everything right. the new harness doesnt have the the connectors for the rs body. should i try to find a harness and ecu for a 92 tpi, or will anything else work?

 

that new harness is probably a stand alone unit meaning all it needs is a power and a ground to run. Tpi electronics will not run an Lt1 to my knowledge, nor will it be worth the swap.

 

Any way to post a pic of what you got?? Here is a link that will get you started on the wiring.
