ECM wires
Hello,
My son has a 69 Chevy C10 that he is installing a Gen.3 5.3L. The person that was working on his truck wasn't able to finish it. So we towed it home. The truck fires up and all. But we noticed there are extra wires coming off the ECM that are connected to anything? Or we need to connect them. Or we don't need to do anything with this wires. Also we noticed that he had a purple wire coming off the ECM hooked to a brake switch. We have another brake switch hooked up already to the steering column. Not sure why he did this. Can someone help us out. Thanks, Ramiro |
