Wiring of a stereo

brown = earth,
grey/red = panel lights,
red/green=permanent memory
white/purple=switchedlive.
that should be the wiring on the car side if it has the original e30 radio loom

Plus twisted pairs of various colours for the speakers, plain white for the control signal to an electric aerial, and, on late models, light blue for speed related volume control.jbh wrote:brown = earth,

A quich question for those in the know: would this feature be an easy retrofit on a car which didn't originally hve the light blue wire ?Brianmoooore wrote: light blue for speed related volume control.

Light blue wire originates at the green connector on the back of the instrument cluster. A lot of E30 clusters won't have the green plastic part of the socket fitted, although the holes where the pins push in are always present.
