BOSCH 1928403110 - 1928404073

Kompakt 1 / Connector 3P / Code 1 / Black

The Component: Genuine Bosch 1 928 403 110 3-way automotive sealed female socket housing plug. Compact 1.1A / Jetronic / EV1 Style 3-position single-row receptacle casing (Black / PA66 GF30 / Sealed / Inline Shroud / Steel Wire Spring Latch / Component Alias Code: 1928403110 / Global Order Reference: 1-928-403-110).

Applications & Fitment: Designed as a premier factory original equipment (OE) harsh-environment connection standard for low-voltage sensor tracking, performance telemetry, and powertrain fuel delivery infrastructure. Widespread across global passenger car, commercial vehicle, marine engine, and professional motorsport platforms, it is exceptionally prominent across European and domestic grids including VAG, BMW, Mercedes-Benz, PSA, and Ford layouts. It serves as the definitive factory female plug interface for three-wire engine components, most notably relied upon for common-rail fuel pressure sensors, crankshaft/camshaft position sensors, knock sensors, external fuel injectors, and auxiliary temperature senders. Engineered specifically to deliver absolute signal continuity and moisture-proof vacuum stability under grueling under-hood thermal cycles and intense engine compartment harmonic vibrations. Highly vulnerable to external steel wire spring clip distortion or loss if pried off carelessly with workshop screwdrivers rather than depressed cleanly during component disconnection, or internal front matrix seal tearing if technicians attempt back-probing with un-profiled multi-meter needles during field electronic troubleshooting.
