This 7-pin plug connects the tractor's electrical system to the implement's wiring harness, transmitting power and control signals for lighting, brakes, and auxiliary functions. It operates across a 6 to 24 V range, making it suitable for both older and modern electrical architectures. The plug's pin arrangement matches the standard ISO 7-pin interface, ensuring correct signal routing between the towing vehicle and the towed equipment. The housing is designed for repeated coupling cycles in exposed conditions. When replacing, verify that the terminal contacts are clean and fully seated before locking the connector halves together.
