Tri-Five w/LS wiring harness

[Hutchracer]

I have a 57 Chevy I am starting on; it will be more than likely LS3 powered. I was wondering what you all are using for wiring harness options. I was looking at a Painless harness but as I am new to the classic car builds, I want to ask opinions. I was always an import car guy but now it is time to do this 57 in tribute to my dad and build it to make him proud. It will be a pro touring build and I have an Art Morrison chassis on order for it, but I want to rewire it for dependability. Sorry if this is basic and has been answered before.

I can't answer your question, but would suggest that you take a look at trifive.com. There is a section there devoted entirely to LS conversions, and I am sure that there will be an answer in the FAQ section. Good luck.

I used an American Autowire Classic Update harness on the trifive builds I have done. Good product.

On my frame off LS builds I use the Painless universal chassis wiring harness. I use Speartech and Howell for the LS wiring harness.

You really can't go wrong with either Painless or AAW. Both are great options.

Thank you guys for the suggestions, these were the options I was looking at but the Speartech and Howell is a new one
