Gmpp ls3 e67 ecu/wiring help please. I have a gmpp ls3 in a 65 corvette. It keeps blowing the 2 fuse's label'ed pt main supply (15a fuse's). I found a pinout in another thread and both those wires go into the black j2 plug on the ecu. What i need to k ow is what they suPply power to so i can start troubleshooting for the short in the system. Or find out why its doing this in the first place. I even called gm performance and they were no help. Said the diagrams i needed didnt exist. Any help would be greatly appricated.
