Yazaki 7122-1864-40 6-Way Male Sealed Connector 

The Component: Genuine Yazaki 7122-1864-40 6-way automotive sealed male tab connector housing. 58 Series W-Type 6-position dual-row inline male cap casing (Light Gray / Nylon 66 / Sealed / 2x3 Grid Configuration / Male Inline Interface Shroud / Component Alias Code: 7122186440 / Global Order Reference: 7122-1864-40).

Applications & Fitment: Designed as a heavy-duty, factory original equipment (OE) wire-to-wire inline coupling solution across safety-critical and high-vibration automotive circuits. This 6-pin male connector shroud is widely integrated across global Japanese manufacturer platforms—including Toyota, Nissan, Honda, and Mitsubishi—serving as the definitive inline link for multi-conductor extension looms and sub-harness break-outs. Most commonly encountered on oxygen sensor (O2) extension harnesses, electronic transmission speed sensors, external lighting harness intersections, and chassis-to-bumper wiring transitions.

Engineered specifically to deliver long-term mechanical stability and absolute waterproof protection under punishing chassis conditions, defending circuits against continuous road spray, dirt build-up, and chemical film contamination. Highly vulnerable to external locking arm fractures if field technicians attempt to pry or force the locking mating system apart during service work without fully disengaging the primary latch, or internal lance track warping if wrong extraction tips are jammed inside.
