( Im beginning to believe it does not exist ! ) Having removed the power train from Chevy#1, and installed same into Chevy#2, and sent Chevy#1 to the SMASHER, did I discover that Chevy#2 has no harness connectors for the ECM. rk ! There are only 3 or 4 wires, how difficult can this be ? Erk ! No wiring diagrams for ECM... some model years have references to ECMs but do not show the ECM harness. HELP ! I have Org,Pink,Brn in a 3-connector and Wht in a 1-connector. Any help is appreciated.
