LS2 Wiring ?'s

[kochevy67]

I am at the point in my project where I thought I was finished with the wiring for the purpose of starting the car. I have a LS2 out of a 2006 GTO, I used the factory harness and rewired my car with a American Autowire harness. I am using a drive by wire throttle as well. The questions I have are concerning the GM harness. There is a rectangular plug white in color that has 13 or 14 wires in it. I was informed that the car will not run unless a select few of the wires are hooked up to something. My question is which colored wires and where do they get hooked up to. The other question I have is concerning a 5 wire black connector that is in the engine compartment on teh driver's side of the motor near the front. I was told the same about that connector. Do you guys have an idea on what I need to do to get the car to fire up besides having the ECM programmed. I appreciate any input you guys have.

I think you probably should have sent your harness off to be modified for standalone operation. They would have sent it back to you with all the necessary connections labelled with instructions. They would reprogram the ECM too. There are several companies that do this, Speartech and Wait4me are two.

If you can read a schematic etc you can probably do this yourself but most send their harness off for mods or buy a standalone harness.

I had John at Speartech make me a harness for the Drive by Wire. I don't think it is necessary to mod the whole harness at this point. These are the plugs I was referring to.

Call Speartech, he's the man!!!

I already called John I just hate to bother him with this partly in fact because I used a factory harness.
