Yazaki 7223-1824-40 58 Series 2-Way Sealed Female Connector Kit (Light Gray)

Restore pristine signal telemetry, clear stubborn sensor faults, and replace heat-damaged factory wiring junctions with this genuine Yazaki 7223-1824-40 2-way sealed female automotive connector kit. Meticulously manufactured to strict original equipment tolerances, this high-performance 2-pin socket housing belongs to the rugged 58 terminal series family and features a distinct light gray orientation profile. Outfitted with an robust internal perimeter locking seal system and high-strength tracking lanes, it provides an uncompromised, weather-tight electrical interface built to endure severe vehicle operating environments.

This specific 2-way configuration is a highly sought-after workshop repair item due to its placement on high-exposure powertrain and cooling components. It is widely used across Toyota, Lexus, and Nissan wiring layouts as a dedicated interface for **engine coolant temperature (ECT) sensors**, ambient temperature probes, and various low-slung chassis actuator switches. Because these connectors sit directly on or adjacent to the engine block, decades of intense thermal cycling, engine vibrations, and fluid exposure make the factory plastic brittle—frequently causing the primary locking tab to snap off during routine sensor changes or cooling system maintenance. A broken tab allows the terminal block to back out slightly under load, resulting in erratic instrument cluster readings or false diagnostic trouble codes (DTCs). This comprehensive repair kit allows workshop technicians to cleanly assemble a fresh, factory-grade pigtail patch right on the bench, saving the immense expense of sourcing a full replacement factory engine harness. It docks seamlessly and locks tightly into its male inline partner component, part number **7122-1824-40**.

### Key Features & Complete Kit Contents:
