The Wilson Trailer APP03907C 7-Way Trailer Receptacle is a heavy-duty electrical connection socket designed for reliable tractor-to-trailer power and signal transfer. This receptacle cross references Phillips 16-7602-28 STA-DRY style sockets, commonly used on Wilson livestock and grain trailers as well as many commercial trailer electrical systems using standard SAE J560 7-way connections.

Built with a durable glass-filled nylon housing, this receptacle resists corrosion, impact, and harsh weather conditions commonly encountered in commercial trucking environments. The STA-DRY design features solid 28-pin contacts and a full-opening lid, allowing easy plug insertion while maintaining a secure electrical connection between the tractor and trailer.

A stainless-steel hinge pin and spring provide long-term durability in demanding fleet and agricultural hauling applications. The unbreakable lid design protects internal terminals from moisture, debris, and road contaminants while maintaining dependable electrical contact for trailer lighting and braking circuits.

This receptacle accepts 0.180 bullet terminals and is designed for heavy-duty truck and trailer wiring harness connections used across many tractor-trailer electrical systems.
