This electrical socket insert provides the mounting and contact interface for the connector that carries power and signals within the header wiring harness. It is the stationary receptacle half of the connector pair, located in the electrical system of the harvesting machine. A damaged or corroded insert causes intermittent electrical contact, leading to sensor faults or actuator failures in the header. As an original component, its contact geometry and retention features match the mating plug, ensuring consistent terminal tension and a weather-resistant seal.
