I bought a mallory distributor online used and I need to know what wires go to what. the part number is 4755101H and it has three wires coming from it. A green wire, and red wire and I brown wire, I know that one is positive coil one is negitive coil and the other is a 12V switch, but I just don't know which is which. I really want to get this done tomorrow, so any help would be great.
