Hello. Do any of you know where I can get the pin outs for the engine to under dash wiring harness under the passenger side of the dash. I already have the pin outs for the ecm and have all that worked out but It is the harness that would connect the computer and the engine wiring harness to the underdash wiring harness. Please help me out if you have any information. I am stumped right now.

 

Do you mean the connector C207?
If so, you can check this wiring diagram page (search for C207) and find the pinout for your year.

is C207 the main plug that connects the engine harness to the dash harness under the passenger side that vats goes through?

 

OK. It is great that I have found the name and some pin outs for this c207 for an 89 camaro. What I am also looking for is where these go? if any go ti ign+ ot ground and what is needed to power the ecm properly and what is needed to power the engine sensors properly. I am getting a lot of coded with my swap and none of the engine sensors are reading on the snapon scan tool. Is there anything on this plug crutial for proper operation. I hafe the pas key module wired up and working but I think I still have some wires not hooked up. If someone could add where each one goes that would be nice.
