I was backing my '01 325i out of the garage last night and noticed the reflection on one of my other vehicles that my right backup light was out. I pulled back in the garage, turned the car off and then back into the "on" position without actually starting it, threw it in reverse and went to check it out. When I opened the trunk the light went on and off intermittently. I then looked at the wires and found this: There's more than one wire broken but I haven't been able to figure out what the other wire is for. All the other lights back there seem to work OK. Looks like I'll be doing some soldering, shrink wrapping, etc. this weekend. Does anybody know what part number the rubber sleeve is and if I could even get the wire with their connectors out of it and into a new one? I've also been doing some digging. Is it true these are 18 gauge wires? I'll probably add a little to play it safe.
