My car is an 05/02 build - I had a short of some kind at the connection to the radio module, which melted much of the wiring harness (not sure if the fuse failed or what happened - I did a search and could find no one else with the same problem). I've purchased a newer BM53, along with a wiring harness, thinking that the superfluous wires for Sirius and the like would be easily distinguished and that BMW would use the same color and gauge of wire for the connections regardless of the year and vehicle in which the BM53 is used. I was wrong. I've matched up all but four of the wires from the car side to the right places on the harness side, but am stuck now. Is there anyone out there who'd be prepared to open up their trunk and take a close up pic of the wiring harness so that I can try to match the wiring insulation colors with the correct spot in the harness/connector? Thanks in advance for any assistance!
