The Component: Genuine Furukawa OEM 3-position heavy-duty sealed female receptacle / Premium Furukawa QLW Series Waterproof Inline Plug Housing / Specialized single-row 1x3 inline matrix layout / Pre-installed with a high-visibility, bright yellow front-loaded secondary locking retainer clip / Integrated top-mounted robust push-down thumb release latch / Constructed from premium, heat-stabilized, impact-resistant Polyamide (PA66) / Component Part Number: QLW-A-B3F-B / Alternate Code: QLWA-B3F-B.

Applications & Fitment: Precision-engineered to deliver completely sealed, moistureproof, and vibration-resistant circuit connections within demanding automotive, commercial vehicle, and marine electrical systems. This authentic 3-pin Furukawa female plug is widely deployed as a specialized factory wiring interface across major Japanese production platforms, most notably matching sensor and valve systems on Nissan and Infiniti models. Common applications include camshaft position sensors, variable valve timing (VVT) controls, exterior mirror electronics, specialized headlamp leveling systems, and select engine management solenoid valves. Developed to withstand the intense thermal cycles and environmental exposure found under-hood or along the lower chassis, its tough glass-reinforced nylon body relies on an internal perimeter rubber seal to keep out oil, road salt, dust, and high-pressure water spray. The pre-fitted bright yellow front faceplate offers absolute terminal position assurance (TPA); when pushed home after wire pinning, it mechanically locks the socket contacts into place to prevent terminal back-out under severe vehicle harmonic vibrations. Crucial stock for professional wiring loom configuration, motorsport harness building, and auto-electrical trade distribution.
