This electrical-system component mounts in the wiring harness of the host self-propelled forage harvester. It serves as a connection or switching point within the machine's control circuits, routing power or signals to downstream actuators and sensors. A failure in this part can cause intermittent or complete loss of function in the subsystem it feeds, such as the header drive or discharge controls. The original part matches the housing geometry and terminal layout of the factory assembly, ensuring proper sealing against moisture and vibration.
