Hinson and PX Drift will modify the stock LS1 harness. I used Hinson and no troubles so far. I have heard good things about PXDrift from a few people.ANVIL wrote:what companys offer wiring for this swap? i cant get to hinson's website right now at work.
Painless and Speartech both make a stand alone system with its own control unit.....well at least the Painless system does. The Painless kit is great from what I have heard......cnichols can tell you more about that if I'm not mistaken....I think he used them. He has one of the cleanest LS1 swaps Ive seen. Its not cheap but I've heard its the bomb. I havent heard much about Speartech other than the fact that it is cheaper.
Frankie at PXDrift is a good guy and will return emails quickly and actually calls you back if you request it on his site. He helped me out a couple times and all I bought from him was a power steering hose.
