It connects the electrical system of a heavy-duty truck to a trailer, providing power for lights, turn signals, and brake controllers. The spring helps protect the cable from bending damage and the zinc die-cast metal housing seals out moisture and road debris. You typically replace this plug when the old one is corroded, the pins are worn, or the spring is broken.
