This electrical socket provides the connection point for auxiliary lighting, control signals, or implement power within the tractor's electrical system. It is installed on the chassis or cab harness and mates with the corresponding plug from a towed implement or accessory. Corrosion or damage to the socket terminals can cause intermittent signal loss or a complete open circuit, preventing the implement from functioning. As an original-manufacturer component, the socket body and terminal geometry match the original assembly's sealing and retention features, so the mating plug locks securely without excessive force.
