Give me a clue! I found a diagram on another forum. From what I can gather 3 wires go together at battery pos., 2 heavy gauge wires, and a yellow voltage sensing wire? Does that sound right? Then there is one white wire connecting the 2 plugs? And finally a wire for the light in the dash? I am going from a 1g on a 1985 ford ltd station wagon. Wiring is driving me nuts! I had to move power distribution and ignition from the passenger side to the driver's side.
