The Component: Genuine Toyota OEM 3-way female plug connector housing. Features a robust 3-position single-row layout configuration 0.64mm (.025) sealed terminal contact footprint / Pre-assembled high-visibility White front-loading terminal position assurance (TPA) secondary lock plate / Premium heat-stabilized Dark Gray Polyamide composite plug body / Weatherproof inline wire-to-sensor socket / Component Part Number: 90980-12A19 / Toyota Order Reference: 9098012A19

Applications & Fitment: Engineered to establish an exceptionally reliable, heavy-duty moisture-proof connection within mid-to-high current Toyota and Lexus engine electrical architectures. This authentic 3-pin Toyota female plug is a critical factory standard across multiple generations of Toyota platforms, widely deployed for high-exposure under-bonnet wiring harness connections. Utilizing a robust 2.3mm terminal profile arranged in a straight 1x3 row, it is explicitly specified to interface with critical engine management components that demand high vibration damping and secure power/signal delivery—most notably three-wire fuel rail pressure sensors, camshaft position sensors, crankshaft position sensors, and heavy-duty variable valve timing (VVT) solenoids. Molded from premium, impact-resistant Polyamide nylon, the heavy-duty plug shell maintains long-term structural integrity and robust latch-arm spring tension under brutal engine bay thermal cycles. The housing features a factory-fitted white front alignment plate that serves as a terminal position assurance (TPA) secondary lock, preventing pin back-out caused by terminal pulling forces or extreme vehicle vibration. Absolute environmental isolation against oil, grease, road debris, and high-pressure water spray is delivered via an internal silicone perimeter seal used alongside individual single-wire seals (SWS). Essential stock for high-end motorsport loom construction, custom standalone EFI wire harness building, and original factory-spec auto-electrical diagnostic field repairs.
