The Component: Genuine Sumitomo high-performance sealed female socket connector plug housing. TS Sealed Series taxonomy / 8-position dual-row matrix female casing / Standard Keying Profile (Black with White Internal Front Holder / Premium PBT / Sealed Waterproof / 2x4 Grid Configuration / Female Inline Waterproof Plug / Component Variant Alias: 6189-7800 / Global Order Reference: 61897800).

Applications & Fitment: Engineered as a premium, original equipment (OE) wire-to-device or wire-to-wire waterproof connection plug designed explicitly for harsh, high-exposure vehicle environments. This 8-pin female multi-row terminal socket block is a highly utilized wiring harness staple across modern Japanese passenger car and motorcycle platforms—frequently deployed in mid-density automotive circuits including accelerator pedal position sensors, complex headlight assembly arrays, body control module sensor sub-junctions, and electronic throttle bodies. It features a robust top-mounted mechanical locking thumb latch that drops securely over the mating male housing's locking ramp, establishing a high-retention hold resilient to extreme multi-axis engine vibration and structural road harmonics. Engineered to conform to demanding international automotive environmental guidelines, its internal silicone perimeter rubber seal forms an absolute barrier against high-pressure moisture ingress, salt spray, road dust, and under-hood fluid misting. Highly vulnerable to thumb latch hinge fracture if field service technicians attempt forced disassembly without cleanly depressing the primary locking handle.
