Cummins / Toyota 4-Pin 4.8mm Oil-Water Separator / Engine Fan Sensor Connector – OEM 7283-7041-40 / 7282-7041-40
Direct OEM-specification replacement for the Sumitomo 4-pin wire harness connector used on oil-water separator filter cup sensors and engine cooling fan circuits across Cummins diesel and Toyota platforms. Cross-references Sumitomo OEM part numbers 7283-7041-40 (female housing) and 7282-7041-40 (male housing). Uses the 4.8mm contact series in black nylon housing — the 4.8mm series is Sumitomo’s high-current connector for fan motor and sensor applications where the connector must carry both high-current motor supply and low-current sensor signals.
