many wires here. the only one that is not documented is a white cable. i assume this is the i bus. since it is serial i only need one cable right?
Most of the e46's are pre-wired for a cd changer, even if you dont have one, theres a good chance the wires are still there.
Its a small square block with 4 pins. Its only 1 cable, thats wot the interface connects to to link to the ibus.
