brown = ground

that's all I know. Take it to someone who knows and don't try to wire this yourself unless you want to fuck it up badly.

Thanks for your input, one wire down, 12 to go, keep them comming.

Any help would be greatly appreciated, until then I'll keep searching the net.

Thanks.

Yellow is left side of car, blue is right side of car.

obviously u bought a new head unit.. and u need to connect the wires... then plug into the harness..they are color coded.. just match the colors

[mmclaren]

Really, Gee if the wires on the harness matched the new unit, would I be posting here for help....

For those who are wondering the colours on the harness do not match the standard colours of the unit.

According to my 1998 328i Bentley manual wiring diagram, here's the breakdown:


red/white = hot at all times
brown = ground
white = antenna amplifier
violet/white = hot in ACCY, run and start
blue/brown = right front high range speaker (this also branches to rt fr low range)
blue/grey = right rear speaker
blue/violet = right rear speaker
yellow/brown = left front high range speaker (this also branches to lt fr low range)
yellow/grey = left rear speaker
yellow/red = left front low range speaker ) this branches to left front high range)
blue/red = right front high range speaker

I don't see a yellow with blue but there is a yellow/violet which = left rear speaker.
Also, your grey/white line is either for the interior light system or amplifier.

I dont know what year and model BMW you have

So what your saying is that you didn't buy an aftermarket wiring harness when you bought your new deck? Makes it kinda difficult if you didn't. But oh well, here's the wiring diagram you seek. I would seriously think about picking up a metra harness, makes things a lot easier...
