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.

 

Are these the connectors?

If so, wiring from both are needed.

 

Yes that appears to be them. The white one definitley and I believe the other one is as well.

 

Do you have any idea what they get wired to? I imagine not all of the wires are going to be used so I was wondering which ones I would have to use and where they go.

 

shoot me a pm with your email address and I'll send you a spreadsheet with the connector wires identified that you will/may need.
