Theres no mention of it in the book??? Could be a power/line filter to stop line noise from the motor affecting your stereo. Generally these are either connected between your positive rail and negative, but i'd recommend speakin to a shop/the shop where ya bought it to be certain. Could just be another earth too to get a better connection, but does this other wire come out of the box too, or does just the black come out and both go in??? Generally speaking though its most likely a filter...

that wire could be anything. On my stock radio each wiree was a different colour even the + and - for each spker was different colours. On my new headunit i got yesterday, the power wire was yellow, and the remote wire was red, which seems as though its mixed up. The purple could be a telephone mute like mine, or a light dimmer like mine has too. Look up the model on the net, or go back to the shop, cos dont wire it up wihtout knowing what it is cos i might fry the head unit

worked it out
thanx for the help
the yellow wasn't power it was some antenna power and the purple was the power which is normaly yellow so yeah dodgy bastards using dodgy colours
