ls wiring

Hey all, I'm eager to get started on this swap. (Still waiting for them to pull everything out) but I wanted to hit the harness first as I wait for things to come in. It's coming from a 04 envoy. Just wanted to know where I should start. I know it needs separated just as pockets guide does but where should I start for the pinouts since I keep coming across just fbody/ls1 pinouts. Or is it basically the same thing?


Also if you see this pocket, when if at all will your pics be back up? Lol Also on a side note I might be interested in one of your harnesses. When it comes to wiring...... i just hate it alot. Haha

Here ya go. I have always used this. Just print them out and grab some beer lol

Assuming you are using a 99-02 F-body computer. If not just look at the vortec wiring. I believe most is similar though.

My first build I used a vortec harness and pinned it for an Fbody PCM, the last one I did was a Vortec harness I de-pinned to start fresh and repinned (minus emissions)

Re: ls wiring

It's from the envoy as well. So I'll go with the vortec one. Must have over looked this. This if absolutely amazing and should get her done. Once I get started I'll have to start a swap thread. Thank you!
