I was wondering what wiring harness every used for their Lsx swap. I was thinking about using TPIS, as they have a good rep, and are about 20 min away.

What did everyone use?

 

If you want to get one that works very well, goto Dana at LT1 Wiring he can set you up by using your original harness and modify it for ease of installation.

 

The problem is I sold my harness with my TPI. Does he also do Ls1?

 

Yes he does, and he does very good work.

 

currentperformance.com there ls1 standalones are incredible im running it right now. and at 650 bucks its a pretty good deal.

 

Well, considering Dana does the same thing for $375.....I don't think $650 is a good deal.

 

I went to their website and it looks like they need your tpi hareness. Thats why its cheaper

 

yeah currentperformance doesnt need any harness. you get a brand new one made from scratch.

 

They don't need the TPI harness, all he needs is the LS1 harness to modify to work with what you currently have, he puts the FP/AC/Fan relays in the harness. A buddy just had one done when he put a 5.3 in a C10 and all he sent was the fbody harness to him.

 

Be aware of Dana at LT1350.com

He will do you wrong. I sent him my Ls1 harness to convert to a Lt1 car. Not only did it not do anything when the key turned but it also fried a $2500 Tech II tool. His wires were all mixed up. Most of the stuff did not work. He would not make it good either. I left many emails and Voice mails. He completely avoided me. I spent countless hours correcting his F-ups. I was very clear on what i needed up front as well.

 

This is the first complaint I've ever heard about Dana. He has done several, and I'm talking around 20 or so for a friend of mine who does a bunch of conversions including the one he put in his truck and have not had one single problem yet.

 

I always seem to get the short end. I just spent 5 hrs studing the Cruise control system because it didnt work. The ls1 pcm # 37 pin Dark green goes to the H slot on the control box. Well he cut the dark green wire coming from the pcm #37 and taped it. Come to find out the LT1 cruise control box does not even have a wire in the H slot. I had to run a wire from 37 to the box. He clearly had to know what he did. That is 1 example. Anyway I am glad my cruise works. The last thing to get working is the TCC unlock from the Brake Switch.
