51254136562 Cable Harness

Electrical wiring harness for MAN trucks and buses, covering power and CAN bus signal routing between control modules, sensors, and actuators in a specific cab or chassis zone. Unlike the full engine harness (which runs the entire length of the engine), this assembly serves a more localised area — typically dashboard electronics, body controller, instrument cluster, or a specific auxiliary system — making it a targeted replacement for a defined fault location rather than a full-system rewire. Failure symptoms include intermittent warning lights on the instrument panel, loss of function in specific cab accessories, instrument cluster data dropouts, or CAN network errors affecting multiple ECUs simultaneously — the last of which is commonly misdiagnosed as module failure before the harness is identified as the root cause. This is a direct OEM replacement supplied to the original connector pin-out and cable cross-section specification. Inspect all connector housings for corroded pins and broken locking tabs before installation — faulty connectors reproduce the same symptoms as a broken harness. Clear all stored fault codes with MAN-CATS after fitting and carry out a full systems check before returning the vehicle to service.
