BMW Engine Sensor Wiring Harness OEM 8632687 — a used genuine part removed from a donor vehicle. This harness connects the sensors on the range extender (0.6L REX) or BEV drivetrain to the control module. A failing harness can cause intermittent sensor faults or a check engine light. Fits both the BMW i3 and i3s, in either the REX or pure EV configuration.
