TE Connectivity 1-1718645-1 (VAG 4F0 973 704) 4-Way Female MCON Connector

The Component: Genuine TE Connectivity / AMP high-performance sealed female receptacle connector plug housing. MCON 1.2 Sealed Series taxonomy / 4-position single-row female casing / Mechanical Coding A Profile (Jet Black Housing Shell / Premium Glass-Reinforced PA66-GF30 / Sealed Waterproof / 1x4 Grid Layout / Female Sensor and Actuator Plug / Component Variant Alias: 1-1718645-1 / Global Order Reference: 1-1718645-1 / Automotive VAG Interconnect Cross-Reference: 4F0 973 704 / 4F0973704).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-device or wire-to-wire waterproof connection plug designed explicitly for ultra-compact, high-vibration automotive engine compartments, chassis arrays, and severe transmission logic environments. This 4-pin female socket block is a core modern diagnostic and systems loom staple across the global Volkswagen Audi Group network (VAG)—prominently integrated inside Volkswagen, Audi, Seat, Skoda, and Porsche factory wiring architectures under component service number 4F0 973 704. It is standardly deployed across multiple critical powertrain and chassis sensory runs, including camshaft position sensors, mass airflow (MAF) sensors, electronic throttle bodies, exhaust gas temperature (EGT) monitors, parking assistance radar nodes, and select LED lighting arrays. It features an integrated high-stiffness mechanical top-mounted thumb locking latch that clicks firmly over the mating male shroud's retention ramp, ensuring an absolute, low-tolerance retention hold resilient to continuous engine block thermal tracking and high-frequency multi-axis structural harmonics. Engineered to conform to rigid tier-1 global factory validation guidelines, its internal cavities pair with clean-body MCON terminals and individual single-wire seals to achieve an IP6K9K environmental rating—providing an absolute barrier against high-pressure steam jet washdowns, road salt spray, track dust penetration, and aggressive oil or brake fluid vapors. Highly vulnerable to internal guide hinge deformation if field service technicians attempt to force removal using un-profiled workshop metal picks instead of smoothly depressing the primary manual thumb lever.
