Sumitomo 6181-0074 6-Way Male HW Sealed Series Connector

The Component: Genuine Sumitomo high-performance sealed male plug connector housing. HW Sealed Series taxonomy / 6-position dual-row male casing / Standard Keying Profile (Dark Gray Housing Shroud / Premium Heat-Stabilized PBT / Sealed Waterproof / 2x3 Grid Layout / Male Inline Harness Plug / Component Variant Alias: 6181-0074 / Global Order Reference: 61810074).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) inline wire-to-wire waterproof connection plug designed explicitly for harsh under-hood environmental conditions, chassis harness extensions, and heavy-duty drivetrain routing. This 6-pin male terminal pin housing is an industry-standard wiring loom repair and harness reconstruction staple across premium Japanese automotive platforms and industrial systems—most prominently integrated within Toyota, Lexus, Honda, Mazda, and Nissan factory wiring architectures. It is standardly deployed across multiple high-vibration engine bay and chassis runs as the direct mating inline partner to the 6189-0133 female connector housing, commonly supporting electronic throttle bodies, multi-channel gearbox control runs, or cabin-to-engine bay passthrough bundles. It features a robust exterior locking shroud with integrated latch ramps that mate seamlessly with the female connector's mechanical thumb clip, establishing a secure, low-tolerance retention hold resilient to continuous engine thermal cycling and intense multi-axis structural harmonics. Engineered to conform to rigid tier-1 automotive manufacturing validation guidelines, its internal dual-row 2x3 cavities accept high-reliability 2.3mm (.090 inch) nominal blade width Sumitomo HW series male pin terminals, utilizing independent wire cavity seals to establish an absolute, waterproof IP-rated barrier against high-pressure washdowns, road salt spray, and aggressive track dust penetration. Highly vulnerable to external locking ramp shearing or rear seal neck cracking over high mileage due to continuous exposure to engine bay heat and road grime, making it a critical service item for professional auto-electrical workshops and harness restorers.
