Hello everyone. I have a 96 suburban K1500 that I am performing a drive train swap in. The 4l60E had last 3 and 4, and the engine had developed a bad knock, so I figured it's time to do some upgrades to get exactly what I wanted. I had been searching for a 6.5 TD suburban for quite a while but had been unable to find one, so I decided to build my own. I have a fresh 6.5 TD installed in the engine bay now, as well as pulling the 4l60E and replacing it with a NV4500. Anyway, right now I am in the process of wiring up the new engine and computer. Now my dilemma/problems. My wiring harness/ecm for the 6.5 is out of a 94. I am in the process of combining the 2 harnesses into 1. I have the complete harness, including the interior harness from the c100 connector inside to the c100 connector in the engine bay. What I am looking for is a pin out of the c100 connector for the 96 5.7 harness, as I have been unable to find it. Any help would be greatly appreciated. Thank you.
