TE Connectivity 1719093-3 (BMW 9201129-02) 4-Way Female Blue Connector

The Component: Genuine TE Connectivity / AMP high-performance sealed female receptacle connector plug housing. 1.2mm Sealed Interconnect taxonomy / 4-position single-row female casing / Mechanical Keying Profile (Signal Blue Housing Shell / Premium Heat-Stabilized PBT-GF Composite / Sealed Waterproof / 1x4 Inline Grid Layout / Female Audio, Speaker, and Subwoofer Plug / Component Variant Alias: 1719093-3 / Global Order Reference: 1719093-3 / Automotive BMW OEM Interconnect Cross-Reference: 9201129-02 / 920112902).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-wire or wire-to-device waterproof connection plug designed explicitly for complex multi-channel vehicle body electronics, high-fidelity acoustic lines, and interior subsystem environments. This 4-pin female socket block is a specialized, highly sought-after wiring loom repair and harness reconstruction staple across modern European vehicle platforms—most prominently integrated within BMW, Mini, and Rolls-Royce factory electrical systems. It is standardly deployed as the primary vehicle-side factory connector interface for under-seat subwoofers, primary door speaker bass modules, and select premium acoustic speaker packages (frequently cross-referenced with BMW factory engineering reference 9201129-02). It features an integrated mechanical top-mounted primary thumb locking lever that clicks firmly over the mating male housing or speaker-side structural retention ramp, establishing a secure, low-tolerance mating hold resilient to extreme low-frequency structural resonance and speaker box acoustic harmonics. Engineered to conform to rigid tier-1 global factory validation guidelines, its internal single-row linear cavities pair with high-reliability 1.2mm nominal tab width clean-body female terminals and high-elasticity silicone single-wire seals to form an absolute barrier against cockpit fluid spills, moisture tracking, fine detailing vapor penetration, and cockpit floor dust accumulation. Highly vulnerable to primary latch tab snapping or hinge fatigue if field service technicians attempt forced extraction with un-profiled metal workshop picks instead of smoothly depressing the locking bar shroud.
