YLCNC 872-689-505 7 PIN Gasoline Pump Plug/fuel Filter Plug DJ7071D-1.2/2.8-200

Automotive connectors are core connection components of the vehicle electrical system, widely used in fuel vehicles, new energy vehicles, construction machinery, motorcycles, agricultural machinery and modified equipment. This 7 PIN sealed auto connector (Model DJ7071D-1.2/2.8-200) belongs to the MWT connector series, a universal aftermarket replacement wiring component specially developed for gasoline pump plugs and fuel filter plugs. It is compatible with Mercedes-Benz W221 vehicles and Yamaha motorcycles. Designed with independent single-wire seals for each cavity, it combines 1.2-series signal terminals and 2.8-series power terminals, enabling stable transmission of sensor signals and medium-load current simultaneously. It is extensively adopted for gasoline pump and fuel filter wiring harness connections of the applicable Mercedes and Yamaha models. Made of PA66 housing material, the connector features excellent high temperature resistance, oil resistance and anti-vibration performance to withstand harsh undercarriage and fuel system working environments. The black PA66 housing is the standard universal color for chassis and engine wiring harnesses, facilitating unified classification and error-proof identification during assembly line production and after-sales maintenance.
