This used OEM BMW door wiring harness (part 9379840) also replaces 61129379840 and 9315126. It is a front, right-side harness removed from a donor vehicle. It handles power and signal distribution to door components like windows, locks, and mirrors. A common failure is broken wires at the door hinge, leading to intermittent window or lock operation. This harness fits BMW X3 and X4 models with several engine options, including 2.0L turbo diesel/gas and 3.0L gas engines.
