The Component: Genuine Kostal high-performance sealed female receptacle connector plug housing. SLK 2.8 Single Wire Sealing (SWS) Series taxonomy / 4-position single-row linear female casing / Code A Standard Keying Profile (Jet Black Housing Shell / Premium Glass-Reinforced PA66 GF30 / Sealed Waterproof / 1x4 Configuration / Female Inline Harness Plug / Component Variant Alias: 9441491 / Global Order Reference: 9441491 / Alternative Manufacturer Reference: 09 4414 91).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-wire or wire-to-device waterproof connection plug designed explicitly for heavy-exposure, high-vibration automotive and industrial powertrain configurations. This 4-pin female socket block is a classic wiring harness staple across major European automotive lines and severe-duty machinery platforms—heavily cross-referenced as a primary service counterpart for VAG (3C0973714), Mercedes-Benz (A0001530842), Ford (4S7T-14A464-AB), BMW (13531436157), and JCB T4I / T4F engine management networks. It is standardly integrated for medium-current under-hood and chassis nodes, including camshaft sensors, pressure regulators, secondary actuator groups, and specialized diesel common-rail system peripherals. It features an integrated mechanical thumb latch that drops securely over the mating male component's locking ramp to guarantee a low-tolerance, positive retention hold resilient to continuous engine thermal expansion and extreme multi-axis structural harmonics. Engineered to conform to rigid tier-1 factory validation guidelines, its internal sealing cavities pair with individual single-wire seals to form an absolute barrier against high-pressure moisture ingress, road salt spray, engine bay dirt, and hot oil misting. Highly vulnerable to latch arm fracture if field service technicians attempt forced extraction with standard screwdrivers instead of applying smooth, central pressure to the primary release lever.
