This used BMW engine wiring harness (module 1), OEM number 8681952, comes from a donor vehicle and is built to factory specifications. As the central electrical loom for the engine, it routes power and signals between sensors, injectors, and the ECU. A worn or damaged harness can cause intermittent misfires, stalling, or a no-start condition—common failure points include chafed insulation or corroded terminals. This harness is designed for the 2.0L turbocharged four-cylinder found in the BMW X3 and X4, ensuring correct connector pinouts and wire lengths for a direct replacement.
