Hope you can help I have a 1999 1.8 lx focus just changed the stereo to a single din unit which has steering wheel input with is three wires + - and input.
I have the control stalk on the steering wheel column. Chased the wires which leads to a plug with three wires.
My question is does any one know which wires are which??? I don't want to start connecting wires in case I blow the stereo.
