This is a used OEM BMW Engine Wiring Harness (module 1), genuine part number 8645494. Also known to replace 8605459 and 7641655, this harness serves as the main electrical conduit for the engine management system. A failing harness can cause intermittent misfires, sensor faults, or no-start conditions due to broken or chafed wires. It was removed from a donor BMW equipped with the 2.0L N20 turbocharged four-cylinder engine.
