  • Speed pulse wire location? Today i had to take the stereo out in my Ford Galaxy 2002. Anyway, as i done it the speed pulse wire (thin purple wire) came away from the yellow plug and now i don't know where it goes.

Does anyone know what pin the damn wire is supposed to be connected to please. Explain in idiots terms:-)
