Original Sumitomo 6189-0887

Includes terminals, TPA 6918-1833 and seals

The Component: Genuine Sumitomo 6189-0887 3-way female automotive sealed connector housing plug. HX Sealed Series 040 (1.0mm) 3-position socket receptacle casing (Black / PBT / Sealed / Inline Housing).

Series Taxonomy: Sumitomo HX Sealed Series System. A premium, high-density Japanese automotive environmental interconnect platform engineered by Sumitomo Wiring Systems. Developed to maintain flawless low-voltage data transmission, minimize contact resistance under high dynamic load profiles, and ensure absolute waterproof insulation across sensitive engine telemetry networks vulnerable to intense thermal cycles and continuous chassis resonance.

Connector Interface: 3-position (3-way) single-row female socket plug layout optimized around an ultra-compact 1.0mm (.040 size) terminal alignment matrix. Designed with high-precision inner tracking channels to cleanly house standard Sumitomo HX series female socket receptacle contacts.

Locking and Sealing Security: Environmentally sealed to an IP67 waterproof and dustproof automotive classification, engineered to operate continuously within a demanding engine bay thermal window. Employs a pre-assembled, high-performance internal silicone perimeter compression matrix seal combined with matching rear single-wire insulation rubber cavity seals (SWS) to completely eliminate moisture tracking, hot engine oil vapors, fluid washdowns, and road grime tracking. Features an integrated, high-reliability top mechanical thumb-latch locking mechanism paired with a matching independent Terminal Position Assurance (TPA) front-lock retainer element (Sumitomo part number 6918-1833) to lock the terminals permanently into position and prevent pin back-out under severe automotive wire harness pulling forces.

Mating Complement: Connects inline wire-to-wire or wire-to-device by clicking directly onto its corresponding 3-way male inline tab partner housing assembly under Sumitomo part number 6188-4739, or coupling seamlessly with factory-installed 3-pin male device component header shrouds.

Common Applications: Extensively specified as a premium original equipment (OE) mainstay across prominent Japanese passenger vehicle networks, tuner platforms, and motorcycle architectures, most prominently within Honda and Acura engine configurations. Universally recognized across the auto-electrical trade as a highly critical wiring harness repair pigtail for K-Series (K20/K24) and B-Series engine rebuilds, as well as Yamaha sportbikes. Most frequently deployed as the factory engine Manifold Absolute Pressure (MAP) sensor plug, Inlet/Exhaust Camshaft Position (CMP) sensor connector, Throttle Position Sensor (TPS) harness plug, and Crankshaft Position (CKP) sensor interface on Honda Civic, Accord, CR-V, and Element models. Also widely utilized as a turbo speed sensor connector on specialized Garrett applications and the tail light interface on Honda Gold Wing GL1800 platforms. Highly vulnerable to primary mechanical thumb-latch snapping from age-related under-hood heat-soak embrittlement, front TPA retainer loss, or internal seat throat distortion if pried open roughly with uncalibrated tools during routine ignition or sensor diagnostics.

Sumitomo 6189-0887 HX Series 3-Way Sealed Female MAP, Cam, Crank & TPS Sensor Plug Housing

Clear persistent check engine lights, eliminate erratic timing telemetry faults, and reinstate maximum factory-standard environmental insulation at your vehicle's safety or powertrain control networks with the genuine Sumitomo 6189-0887 3-way female sealed connector housing plug. Precision-manufactured to strict Tier-1 original equipment global automotive engineering metrics by Sumitomo, this 3-pin HX Series 040 socket carrier block is an indispensable piece for executing professional sensor pigtail restorations, custom motorsport wire tucking, and clean auto-electrical loom overhauls. Engineered explicitly to survive punishing dynamic forces directly on the cylinder head, intake manifold, or transmission case, it establishes a solid, zero-clearance conduction channel that safely routes critical logic data lines, signal loops, and low-voltage current paths.

The 6189-0887 carrier housing is injection-molded from a premium, heat-stabilized Polybutylene Terephthalate (PBT) compound finished in a factory black profile, ensuring outstanding structural impact defense, high dimensional tracking stability under severe thermal loads, and complete immunity to chemical degradation from hot engine oils, fuel vapors, and environmental road salt spray. Working in absolute uniformity with its high-grade internal silicone perimeter seal and rear single-wire insulation seals (such as 7165-1075), it forms an impenetrable barrier that isolates the active terminal lanes. This authentic replacement component allows independent tuning garages, diagnostic auto-electricians, and custom JDM engine builders to deliver reliable, zero-resistance factory harness overhauls.
