Hi guys,
I'm new to this forum and have just been given an 1991 100 quattro. The car required a new starter and had the older one removed before I received it. I just got a newer used starter and now have no idea what wires belong where. There is a yellow wire which I'm assuming is the power, and a black one which I think is the ground. On the starter itself there are two leads, one that has a wire attached and one that does not. Can anybody tell me what terminals on the starter these wires belong to?

Also is it advisable to use a universal accel coil on this car?

Thanks all for any replies,
Dan
