Sumitomo 6189-7039 4-Way Female HV/HVG Sealed Series Connector

The Component: Genuine Sumitomo HV/HVG Sealed Series 4-way female plug connector housing. Features a high-reliability 4-position dual-row matrix (2x2 layout configuration) / Ultra-compact 1.0mm (040) micro terminal blade size footprint / Pre-assembled high-visibility Gray front-loading terminal alignment spacer and lock plate / Premium heat-stabilized Black Polyamide (Nylon) composite plug body / Weatherproof inline wire-to-wire socket / Component Part Number: 6189-7039 / Sumitomo Order Reference: 61897039.

Applications & Fitment: Engineered to establish an exceptionally dense, moisture-proof multi-circuit connection within automotive electrical architectures where space is at an absolute premium and vibration resistance is paramount. This authentic 4-pin Sumitomo female plug is a major factory standard across modern Japanese vehicle manufacturing lines, widely deployed for OEM wiring harness connections across modern Toyota, Honda, Nissan, and Subaru electrical setups. Due to its micro-precision 1.0mm terminal profile arranged in a square 2x2 grid, it is extensively specified to interface with compact engine management components, oxygen sensors (O2 sensors), mass airflow (MAF) sensors, electronic throttle bodies, and high-performance ignition coil pack links. Molded from premium, impact-resistant Polyamide nylon, the heavy-duty plug shell maintains long-term structural integrity and robust latch-arm spring tension under harsh engine bay thermal cycles. The housing features a factory-fitted gray front alignment plate that serves as a terminal position assurance (TPA) secondary lock, preventing pin back-out caused by terminal pulling forces. Complete environmental isolation against oil, grease, road debris, and high-pressure water spray is delivered via an internal silicone perimeter seal used alongside individual single-wire seals (SWS). Highly sought after for high-end motorsport loom construction, custom standalone EFI wire harness building, and original factory-spec auto-electrical diagnostic field repairs.
