7283-8855-30 8-Way Female Sealed Housing

The Component: Genuine Yazaki 7283-8855-30 8-way automotive sealed female plug connector housing. RH Series 8-position dual-row socket receptacle casing (Dark Grey / PBT / Sealed / 2x4 Grid Configuration / Integrated Terminal Position Assurance / Component Alias Code: 7283885530 / Global Order Reference: 7283-8855-30).

Applications & Fitment: Designed as a premium factory original equipment (OE) heavy-duty connection interface for modern low-voltage sensor grids, complex engine control units, and lighting wire distributions. Exceptionally prominent across global Japanese vehicle architectures—including Toyota, Lexus, Nissan, Subaru, and Mitsubishi platforms—it acts as a definitive factory replacement plug for multi-wire configurations. Most commonly encountered on oxygen sensors (O2), electronic throttle bodies, mass airflow sensors (MAF), and high-vibration headlight or tail light harness links. Engineered to deliver exceptional mechanical stability and continuous watertight vacuum protection within harsh automotive micro-climates, guarding circuits against continuous splash water, road grit, and under-hood oil film contamination. Highly vulnerable to top-latch thumb lever cracking or snapping if technicians attempt to disconnect frozen connections aggressively in cold weather without venting the lock, or internal terminal alignment tab distortion if incorrect extraction tools are wedged into the front mating face during pin removal.
