ls1 wiring harness question - Lateral-g Forums

blazen · #1 08-14-2005, 11:36 AM

I’m currently putting a ls1 in my 72 chevelle. I was look around for wiring harness, and a reprogrammable computer that I can hook up to my laptop, I saw the Accel DFI kit, but I really don’t feel like spending $2,600 for it. does any own this kit or know someone with it. I would like to hear some commits or other types of wiring kit out there before I buy one. And for those that have a ls1 powered vehicle, what wiring harness did you use stock or aftermarket. Thanks for your time, Alex

I am modifying my stock harness. If your looking for plug and play, TPIS has a very nice harness, and just lowered thier price to around $475. It looks very sanitary(compared to the Painless one).

They did an excellent job modifying my harness to meet my specific needs and the pricing is very good.

I'll second that, John was great with mine.

If your motor is stock, or has some mods I would just re-use the stock harness and computer and have them modified by John at Speartech.

yeah have your stock harness worked. And you can use HPTuners for tuning on your laptop.

I’m still new at this but what is the difference between the stock wiring harness and the Speartech harness, just wonder, I’m still going to order the speartech because my motor didn’t come with a harness. Thanks for your commits, Alex

Speartech reworks stock harnesses or he builds them from scratch too I believe. He can make leads as long as you need them to be so you can mount the PCM pretty much anywahere you want. Ive heard nothing but good things about his work.
