Guest FrantiC Report post Posted October 26, 2009 e30 isn't colour coded. Pretty sure its the brown/purple wire that is the switched +!2V (acc) joins to red. You can figure out the wires with a multimeter which is the constant +12v, which is the switched +12v, etc. Quote Share this post Link to post Share on other sites
Wervie67 0 Report post Posted October 26, 2009 the two e30s ive worked on have been colour coded (both pfl if that makes a difference) but your right, multimeter's do save alot of time. and for speakers, just use a battery. Quote Share this post Link to post Share on other sites
