Yazaki 7282-3440-40 3-Way Male Unsealed YES/YESC Connector

The Component: Genuine Yazaki 7282-3440-40 automotive unsealed male pin tab connector housing. YES/YESC Series taxonomy / 3-position single-row linear male inline casing (Dark Gray / High-Impact PBT / Unsealed / 1x3 Grid Configuration / Male Inline Interface Cap / Component Alias Code: 7282344040 / Global Order Reference: 7282-3440-40).

Applications & Fitment: Engineered as a space-saving, factory original equipment (OE) wire-to-wire connection block designed for non-waterproof interior cabin networks. This 3-pin male tab terminal plug is a foundational harness component across modern Japanese passenger vehicle platforms—most notably utilized throughout Toyota, Lexus, Nissan, and Mitsubishi cabin assemblies. It is heavily specified for low-to-medium current distribution systems where localized moisture sealing is unnecessary, such as overhead console lighting feeds, dashboard switch clusters, interior proximity sensor loops, steering wheel clockspring sub-harnesses, and cabin entertainment links. Designed specifically to provide high retention and clean insertion clicking, it protects critical low-voltage tracks from micro-vibration dropouts. Highly vulnerable to rear hinge lock crisping or outer lock track fractures if field technicians roughly lever the housing with un-profiled hand tools during cabin teardowns or device upgrades.
