Having problems with your Cars & Trucks ?
2002 Saturn vue engine computer was sent out to be rebuilt and was unrepeatable. A replacement was reprogramed and returned and there are pin numbers I'n the sockets but I can't find numbers on the wiring plugs I'n the engine and they look like they are identical with the exception of a blue band around the wires on one. The other is black. How do you tell which one plugs I'n which socket. They definately look the same. I don't want to ruin the new one by crossing them up. What am I missing?
