Bosch 1928402571 Jetronic 2-Way Female Connector Housing 

The Component: Genuine Bosch high-integrity automotive wire-to-device female connector housing. Jetronic EV1 Core Series taxonomy / 2-Position (2P) single-row female receptacle plug structure / Code 1 Keying profile / High-density glass-fibre reinforced polyamide (PA66 GF) body / Integrated internal perimeter axial seal / Heavy-duty engine management, fuel injection, and sensor matrix interface component / Component Part Number: 1 928 402 571 / Bosch Order Reference: 1928402571 / Bosch Trade Number: VNP-JETR-2/3P / Global Logistics GTIN: 3165141988710.

Applications & Fitment: Engineered as the definitive original equipment (OE) specification 2-way connection standard across commercial and passenger automotive sectors. This heavy-duty female Jetronic housing is universally recognized as the standard interface for classic and modern top-feed fuel injectors (EV1 style), fluid temperature sensors, crank/cam position pickups, solenoid valves, and ignition system components. Widely utilized across major vehicle platforms including Mercedes-Benz, Fiat, MAN, and VAG, this housing is built to thrive in extreme engine compartment environments. It features a robust, hand-released spring-steel wire clip that provides a positive mechanical snap-lock onto mating device headers, eliminating terminal back-out under severe vibration. The connector relies on a lance-locking primary terminal retention system to accept standard 2.8mm width blade terminals (such as Junior Power Timer or similar series). When combined with appropriate single-wire seals, it delivers a completely moisture-proof, environment-sealed link that prevents ingress from oil, fuel, and road grime. Ideal for heavy-duty wiring loom builds, motorsport harness fabrication, and direct workshop electrical repairs.
