LS harness ?

Rockwells607 · Sep 4, 2015

Time to join the 21st century , I bought an 05' TJ off here a while back and I have a pile of decent parts laying around from past projects that I can throw at it and make a pretty fun decent road and trail rig, tons, LS , 38 sxs on h1s, hydro assist etc. anyways my question is who and where is decent on cutting down LS harnesss , I have a stock 6.0 outta an 04' van and Id just like to have the harness done and computer tuned or whatever they do. Any recommendations and ideas? I Don't wanna tear into the motor just tune and cut the harness decent power and fuel mileage is all im after nothing crazy I have two buggies for
That , I plan to run a turbo 350 and upped Dana 300 with 4:1, 4:10s in the axles because I have all that already exept the tranny-

Get a psi harness. $500 for a brand new harness. Can't beat that

Cut it down yourself it's very very easy just takes a couple hours. An send your computer to black bear ( look them up on fb) an get them to put a custom tune in it.

I have the links saved that I used to do my harness if u need them. All u gotta have is 2 fuse boxes an a fuel pump relay

I used the info on lt1swap.com and did my own harness as well. About 6-8 hrs total.

I sent the computer to http://www.150tunes.com/. Wayne Hartwig is over on Pirate in just about every LS tuning and wiring thread. He was really easy to deal with. The nice thing is that for $150 they will re-tune or adjust things for life. You just pay shipping. They have a guy who does harnesses though too. If you don't want to mess with it yourself. I would just box it all up and send to them.
