Sumitomo 6189-7037 3-Way Female HV/HVG Sealed Series Connector

The Component: Genuine Sumitomo HV/HVG Sealed Series 3-way female plug connector housing. Features a ultra-compact 3-position single-row layout / 1.0mm (040) micro terminal blade size footprint / Pre-assembled high-visibility Cream/Off-White front-loading terminal alignment lock plate / Premium heat-stabilized Black Polyamide (Nylon) composite plug body / Weatherproof inline wire-to-wire socket / Component Part Number: 6189-7037 / Sumitomo Order Reference: 61897037.

Applications & Fitment: Engineered to establish an exceptionally reliable, space-saving multi-circuit connection within automotive electrical architectures that demand maximum moisture protection and vibration resistance in restricted spaces. This authentic 3-pin Sumitomo female plug is a factory standard within leading Japanese vehicle production lines, widely utilized in OEM wiring harnesses across modern Toyota, Honda, Nissan, and Subaru models. Due to its micro-precision 1.0mm terminal design, it is heavily specified to interface with compact electronic engine sensors, camshaft positioning sensors, specialized variable valve timing (VVT) solenoids, localized pressure switches, and auxiliary exterior lighting systems. Molded from premium, impact-resistant Polyamide nylon, the resilient plug body maintains superb structural stability and latch tension under prolonged engine bay heat exposure. The housing features a factory-fitted front-loading retainer plate that securely holds the terminals in position to eliminate pin back-out under harness tension. Complete environmental defense against high-pressure water washdowns, grease, and road salt is achieved by combining the housing shell with an internal silicone perimeter seal and individual single-wire seals (SWS). An essential component for motorsport loom construction, custom EFI wire harness assembly, and original factory-spec auto-electrical diagnostic field repairs.
