HARNESS for LSA..
 

Hello, ripped out my dash and did some celan up work on both sides of the firewall. I want to take advantage of the easy access and do all of the wiring, AC, ducting before i weld the dash in.

I was looking at the GMPP http://store.chevroletperformance.co...-19201861--%3E
but was wondering if their might be a better route? Also I may go LSA can I purchase a harness that will work on LS3 or LSA and pick up the controler later?

My personal preference for harnesses is Speartech. Always excellent work and they will build the harness exactly how you want it.

(distance from engine to ECU), do you want a/c request/pressure sensors, auto or manual trans.

The Speartech harness is lays out nicer in the engine compartment (IMO) and also the fuse box included with the GMPP harness is on the large side so harder to manage a clean install.

I bought one from BP automotive, happy with how it turned out. Price was great, compared to others

I used modern vintage systems and I am very happy. Everything is custom built to your specification. If you need contact info let me kbow..

I am going to run my battery in the trunk, 69 camaro convertible with LS3 and TKO600. Whos harness accomadates a battery in the trunk?

I second Speartech.......John is the Best!!!

got contact info? let voice mail and email... crickets...

Yes please... PM me if you can

Also check Howell and PSI. I had a local GM EFI engineer/car builder suggest Howell for a clean instal. I am still shopping also.

LSA harness and ls3 are different especially if using a gm controller. Just letting you know. If you go aftermarket like MAST you may be able to swing it both ways
