Sumitomo 6187-3271 3-Way Male MT Sealed Connector with Clip

The Component: Genuine Sumitomo MT Sealed Series 3-way male tab connector housing with pre-installed wing mount chassis clip. Features a compact 3-position triangular clover-leaf layout / 2.3mm (090) terminal size profile / Integrated external arrow-head body panel clip / Premium raw Natural-White heat-stabilized Polyamide (PA66 Nylon) body / Complete weatherproof inline wire-to-wire plug / Component Part Number: 6187-3271 / Sumitomo Order Reference: 61873271.

Applications & Fitment: Engineered to provide uncompromised low-voltage circuit connection and secure structural anchoring within high-vibration automotive engine bays and exposed chassis locations. This authentic 3-pin Sumitomo male plug is equipped with an integrated arrow-head style push mount wing clip, allowing the entire wire assembly to be snapped directly into standard factory sheet-metal holes or bracket assemblies to completely eliminate wire chafing and loom movement. It is widely specified across major Japanese vehicle manufacturing architectures—most notably within factory Toyota, Honda, Nissan, and Subaru engine wiring looms—to terminate high-exposure components such as speed sensors, specialized oxygen sensors ($O_2$), localized camshaft sensors, and auxiliary sub-harnesses. Molded from premium, raw PA66 nylon polymer, the structural shell offers excellent dimensional consistency, high impact resistance, and deep chemical immunity against fuels, lubricants, and road salt solutions. Environmental isolation is accomplished by pairing the housing channels with an integrated internal black silicone perimeter seal alongside individual single-wire seals (SWS), achieving a robust waterproof barrier. An indispensable original hardware item for high-level EFI loom building, custom motorsport wiring harness assembly, and precise factory-spec auto-electrical field repairs.
