Crane Hi-6S users, I need your help
Hello all! I have a Crane Hi-6S I'm trying to use, but having trouble figuring out the wiring. I have it wired up as the diagram shows on my 1988 Mustang Coupe. For some reason it will not start. The status light blinks as its turning over. Out of one loom, it has a red, white, and black wire. I know where the red and white wires go, but where does the black go. I have the heavy black wire grounded to the body. Any help with this will be greatly appreciated.
