Default Harness and ECM
What harness should I get for my v8 swap? I am told 94 and 95 (OBD I) is non-programmable. True or BS? The motor is from a 94 caprice cop car and going into a 94 Camaro originally a v6. Will a 1996 Camaro OBD 2 harness and ECM work? Or do I have to stick with the appropriate year? I am also worried the 96 might not work in conjunction with the 94 VATS system. Please tell me my options. This is a budget build and I am not looking to spend hundreds on a aftermarket ECM and harness, but I might send in the harness to make it a stand-alone system.

That's BS. They are all programmable, even the 93 (but you need a chip burner). Go with a 94 or 95 harness+pcm. Much easier to wire up and tune as opposed to OBDII

I have a 94 Z28 m6 that I'm removing the engine harness and pcm from the car because I'm swithching to the EFI connection 24x setup with an LS1 pcm and custom harness. Give me $250 + shipping and you can have both, they should be out of the car in the next few weeks, so let me know. Fastes way to reach me is email aero.coupe@hotmail.com
