87 sierra
I'm helping a buddy of mine do a LS swap into his sierra, he's got a 87, how much of his old ecm wiring do we need to leave in if any? my swap was a 84 so i didnt have any of those electronics.
i havnt been on here much since i had to get a job...

Re: 87 sierra
I believe that some of the harness folks like the guys below can make you a custom harness that will connect with your factory bulkhead. Give them a call. I know there are others, these are highly regarded on ls1tech.
