TE Connectivity 1-967642-1 3-Way MQS Sealed Female Connector (Mercedes 2105402181)

The Component: Genuine TE Connectivity / AMP 1-967642-1 3-way sealed female receptacle connector plug housing. MQS (Micro Quadlok System) Series 0.63mm contact classification / High-grade glass-fiber reinforced PBT-GF15 / Code A keying / Jet Black.

Applications & Fitment: Designed as a factory original equipment (OE) heavy-duty, watertight wire-to-wire or wire-to-device terminal housing. This 3-position female plug is standard utility equipment throughout European automotive wiring looms—most notably across BMW, Mercedes-Benz, and VAG (Volkswagen, Audi, Seat, Skoda) powertrain networks. It is the definitive factory choice for low-current engine management linkages, including camshaft position sensors, crankshaft speed sensors, oil pressure switches, ambient external temperature telemetry, and small electronic actuator feeds.

Engineered to provide exceptional mechanical retention under severe vibration and continuous under-hood thermal cycles. Highly vulnerable to exterior thumb locking lever failure if forced during cold-weather diagnostic maintenance without releasing the latch, or internal track deformation if un-profiled steel probes are rammed into the front face for electrical continuity checks.
