Trying to install an electric fuel pump in a '73 sedan. There is a wire coming out of the floor right where I need it, but I can't figure out what it's for. I can't find it on the diagram. it has just under 12vdc with the key on, but wouldn't spin the pump. It's a brand new pump, and spins when hooked to the battery. Any ideas? If I have to run a new wire, where would it come from?
