This BMW X3 Door Wiring Harness (front left, OEM 3450836) is a used genuine component. The harness, also superseding 3450837, was removed from a 3.0L 2996CC L6 GAS DOHC naturally aspirated donor. It connects power, lock, mirror, and speaker circuits through the driver's door. Common failure: broken internal wires from repeated flexing, causing intermittent window or lock operation.
