The Component: Genuine Sumitomo OEM 4-position sealed male tab inline housing / Premium Sumitomo MT Sealed Series waterproof wire-to-wire connector plug / 4-way 2x2 square-grid cavity configuration / Integrated slide-on mounting bracket track for secure chassis-panel clip mounting / Molded from premium, impact-resistant, heat-stabilized Nylon 66 / Component Part Number: 6180-4181 / Alternate Engineering Identifier: 61804181.

Applications & Fitment: Exceptionally reliable, weatherproof, and dust-proof electrical wire-to-wire interface engineered for medium-power distribution, sensor links, and auxiliary circuits on classic and modern Japanese automotive platforms—widely utilized by Toyota, Honda, Nissan, and Mazda. This authentic 4-pin 2.3mm (090) Sumitomo male housing block is an industry-standard for under-hood, exterior, and chassis wiring looms, frequently specified for O2 oxygen sensors, compact alternator circuits, distribution junctions, and custom motorcycle wiring assemblies. Designed to withstand harsh road spray, high-pressure engine bay washing, and continuous drivetrain resonance, its tough Nylon 66 shell ensures a rigid structural interface. The integrated bracket track on the housing body allows the connector to be snapped onto standard vehicle frame clips to prevent harness rattling and wear. A key stocking item for professional wire-harness manufacturers, restoration specialist workshops, and automotive trade wholesale supplies.
