ok so what would ne connected to the mk1? the switched 12 volt ignition key power right? so where would that go in the mark2? next, and i know this is a real hard question for you to answer, but what would the constant 12 volt power look like? there is got to be a defining characteristic. like a label on it or something. i have a ford explorer if that helps. it should be right there with the other wires right or would additional wires be needed to make it longer or something?
