This used BMW door wire / wiring harness, OEM part number 6878834, is a genuine original-equipment part removed from a donor vehicle. Also called a door wiring harness, it connects power windows, door locks, speakers, and mirror controls inside the front left or right door. A failing harness often causes intermittent window operation, non-responsive locks, or audio dropouts. It fits BMW Z4 models with either the 2.0L turbocharged I4 or the 3.0L turbocharged I6 engine.
