I didn’t realize the alt I have is 3 wire compatible.. I looked and didn’t see a plug. It was capped on the inside. I bought a small wire adapter that should solve the issue. 2 more unidentified wires and I’ll be looking to start it up! Not sure if this is part of the new harness or part of the efi. They are connected together and were attached to the positive side of the coil. Anyone?
