PSI conversions, Speartech, and Painless (less plug and play). All will require some simple wiring into the OEM system.

Re: Does anyone still make a plug and play swap harness?
AC and chassis harness are separate and you can retain the stock ones. For an LS swap you will be replacing the engine harness and providing power to the harness and ECM. Depending on what exact set-up you do, will determine how you retain functionality of the gages. There are some good wiring writeups in the stickies at the top of the forum.

If you're on Facebook, look up Nathan Wei. He posts on some of the thirdgen pages and does custom harnesses. No personal dealings with him, but his harnesses look great in the pics he posts and there are usually comments from people who have dealt with him.

Is he is still willing to make them I agree with this route. I have seen his custom harnesses in person and they are incredible thorough to your specific needs. There is a higher cost of entry, but truly plug and play into the 3rd gen platform.

is it drive by wire by?
There is a minor difference between 90-92 V6/TPI and 90-92 TBI, but it's something you can do as an end user with a small screwdriver and short length of wire

Pocket, do you do wiring harnesses in your shop. I think I remember you living in NC.
Re: Does anyone still make a plug and play swap harness?
I own a shop in Lexington NC. If you want to bring the car down, I'll be happy to wire it through the business. I am not doing mail order harnesses anymore though

Lexington is a hick for me from Raleigh. What is the shop name and I will keep it in my phone in case I hit a snag and need a shop for help.
