who makes the best and most simple wiring harness to put a fuel injected cam'd ls1 in a old camaro or would it be best to buy a motor with the factory harness on it already...thanks

Well we have 2 sponsors on here that sell them PSI and Speartech. Personally went with PSI because of the reviews I've read on here and his presence on these boards. I havent installed it yet but appears to be of good quality.

I do my own, but if I wanted a nice simple harness I would go with PSI. Jon is on this board helping anyone, and what I have seen of their harnesses looks good.

would it be better to use the psi harness for my swap than using the factory harness...and im trying to figure out how the charging system will work with either harness using the factory ls1 alternater...any help would be appreciated...thanks billy

Ive used both PSI and Speartech, both are quality units. The PSI is a new harness and the ST unit was a re=do of my harness..The PSI was a little less money but didn't include a check engine lite and the wires aren't labeled. ST's included both.....course the CE lite was only 2.95 from Radio Shack but had to install it myself....YOU can't go wrong with either one...

All I want is for the truck harness not to drape over my LS1 intake. I will be making some covers to cover the fuel rails and coils

Is there a cheaper method to accomplish this than spending $500 on a harness?

Yeah, take your time & make it yourself. That way you can make every wire just how you want it to be.

Wiring isn't on of my strengths....but if I gotta I gotta

This was a truck harness, reworked to mount behind my passenger fenderwell. Everything runs out the back and over.
