Product Overview
The WA15-720 7-way trailer socket is a 7-pin round (SAE J560 style) vehicle-side connector used to provide electrical connection between truck and trailer.
This socket features a zinc die-cast housing for durability and corrosion resistance, along with split pin terminals for secure wire insertion and reliable conductivity. It is designed for standard heavy-duty trailer wiring systems and is commonly used on tractors and trailers requiring a 7-way round connection.
Built as an aftermarket replacement for Phillips 15-720, this connector is used to supply power for lighting, brake signals, auxiliary circuits, and ground between vehicle and trailer.
