Sumitomo 6180-4771 MT Series 4-Way Female Sealed Plug

The Component: Genuine Sumitomo 6180-4771 4-way female automotive sealed connector housing plug. MT Sealed Series 2.3mm (.090) 4-position single-row socket receptacle casing (Natural / PBT / Sealed / Inline Housing / Loose Piece / Suzuki Cross-Ref: 09900-28710-012).

Applications & Fitment: Designed as a primary factory original equipment (OE) wiring harness repair pigtail for harsh, high-vibration environment sensor and fuel circuits. Widely specified across Suzuki motorcycle platforms (notably the 2001-2002 GSX-R1000 fuel pump and sender chassis harness side), KTM installations, and universal Japanese import grids as a high-reliability oxygen (O2) sensor interface plug. Highly vulnerable to primary locking-arm failure from age-related thermal exposure or contact lane distortion caused by aggressive back-probing during workshop multi-meter troubleshooting.
