I may have back feed the pcm. If so is the rest of it still going to function. I can rewire the fans to come on when I start the truck. I will have to get my mechanic to re scan it. when I wired the a/c fans I spiced into the fan wires after the relays so I don't see how I could have back feed the pcm as it would go through the relays on the hot power sides 12volts and not gone through the relay switch side which the pcm ground wire (dark green and blue) is connected to. here is my wiring. I know not easy to read but I am old. LOL
