Sumitomo 6040-3111 MTW Series 3-Way Female Housing

The Component: Genuine Sumitomo 6040-3111 3-way automotive unsealed connector housing plug. MTW Series 2.8mm (110) Type 3-position single-row female socket inline receptacle casing (Natural White / Black Variant / Nylon 66 / Unsealed / Cable Mount Inline Plug / Mating Tab Width 2.8mm / Trade Designation Cross-Ref: MTW-3S).

Applications & Fitment: Designed as a primary factory original equipment (OE) non-sealed inline connection solution for low-voltage signal distribution and auxiliary power loops. Universally recognized across vintage and modern Japanese motorcycle architectures (prominently featured on classic Honda, Yamaha, Suzuki, and Kawasaki wiring harnesses) and legacy automotive sub-assemblies. Most notably specified as the definitive female inline interface for vintage stators, handlebar switch assemblies, ignition sub-looms, rectifier layouts, and custom aftermarket electronics drops.

Engineered to provide a low-profile, clean-mating inline joint within dry vehicle zones like inner fairings, main frame rails, or under-seat trays. Highly vulnerable to structural latch cracking if pried roughly during cold climate servicing, or internal wall tracking distortion if back-probed carelessly using raw, un-profiled multimeter test needles during field electronic troubleshooting.
