Also - it's important to remember that you get what you pay for. There are a couple in the list above that I don't recognize, but Speartech has a really good reputation.
Good luck with the swap.

Re: LS1 SWAP IN 1990 CAMARO
i went with current performance and they are great all the wires you need to splice in to the old harness are labeled and they also put a stand alone fuse box and relays for the engine and put in an ob2 port for programming,
with the modified harness and reprogramming of my computer it came to like $640 with shipping back to me in va, but i also have just a basic stock ls1 set up!

And you do know to get rid of the stock harmonic balancer of the LS1 engine you drop in there before you drop it in unless it already has an aftermarket one right?

I'm in the wrong business.
People need to start sending me their ls1 harness and ls1 fuse blocks from their donor cars and I'll modify them for the fire sale price of $500

How long would it take you to get the wiringharness done and back to me for the install because I live in florida and is there anything you recommend I get for the ls1 swap

Do a search at the top of the site. Search for posts by username Pocket. You'll find tons of posts by him. Click on his name and send a personal message. You're new to forums in general I'm assuming?
