Ok here's the deal. First of all this is my first project and though I have read until I can't keep my eyes open anymore on this forum. I decided to buy a new engine instead of buying a donor car. I have an ls376 480hp version. It's going in my 91 Camaro. Since I bought it new I don't have a ecm harness yet. Looks like how ever I go it's going to be real expensive. I know Hawks can build me a basic plug and play harness but that alone is $1000.00 plus I need to still buy an ls3 harness to mod. Any suggestions appreciated. I am not going to try and make a harness my self. I am an older guy and eyes aren't perfect and don't even consider that as an option. Also this is going to take quite a while before I have everything I need so I really don't want to pull the tbi harness out of my Camaro. I see them for around $125.00 on eBay so I guess that would be a way to go. Thanks in advance.

 

There's a guy on here, I think his name is Pocket, that also builds those harnesses. You might try searching for posts he has made and then PM him.

Other than that, I'm a do-it-yourself-er.

Good luck!

 

Thanks for the advice. I will contact him.

 

Look into the GMPP controller kit for that ls376/480. It comes with everything you need.

(Edit- GMPP=GM Peformance Parts)

 

+1 for pocket!

great member on the forum, with lots of knowledge to share. he just finished my harness today.
