Applications & Fitment: Engineered to deliver exceptionally secure, low-resistance, and completely waterproof connections in high-vibration automotive environments. This authentic 3-pin Sumitomo MT series female plug is widely utilized across major Japanese automotive brands, motorsport auxiliary looms, and marine electrical subsystems. Operating with the robust 2.3mm flat terminal socket footprint in a straight 1x3 matrix, it is heavily specified for medium-current components such as vehicle speed sensors (VSS), camshaft and crankshaft position sensors, windshield washer pumps, auxiliary lighting links, and early-generation distributor connections. The rugged outer shell features a top-mounted mechanical thumb-latch surrounded by elevated protective shoulders, effectively shielding the lock mechanism against accidental release from pulling wire harnesses or nearby mechanical interference. Full environmental isolation against extreme moisture, engine fluids, dust, and salt spray is accomplished by an integrated orange silicone interface ring combined with independent 2.3mm wire seals. Essential inventory for professional wiring loom fabricators, diagnostic auto-electricians, and automotive component wholesalers.
