Check into the Auto Crossmember.. Where you getting the LS Harness & PCM?

The LT1 Engine Harness or PCM will not work.

I have a 2001 LS1 harness that is wired for plug and play in my '97 Trans Am. I may be putting it back to stock, and I will be selling the harness if I do. It is also wired for both A4 and M6 transmissions, and I have run it with both. It's pretty bad ***

It's to wire a LS Engine Harness into the LT1 Chassis Harness..you will need a LS Engine Harness & PCM to run the LS Engine.

The 2008 setup will partially work. The Harness can be re-worked, but you will need the PCM from a LS1 F-body.
