This is a 7-Way Blade Style Vehicle End Electrical Connector, identified by manufacturer part number 16695 from JMK-IIT (also known as IIT). It is designed to establish a secure electrical connection between a tow vehicle and a trailer, functioning as the female socket on the vehicle side. The connector transmits various electrical signals including tail lights, brake lights, turn signals, reverse lights, and can also provide auxiliary power or control for electric brakes. Constructed with a heavy-duty ABS housing and solid brass contact blades, it resists impacts and corrosion. Features include clearly marked terminals for easy wiring, set screws to firmly hold wires in place, and a spring-loaded cover to protect terminals from environmental elements when not in use. This connector is commonly used in 12V DC applications and meets the requirements of the SAE J560 standard for heavy-duty truck and trailer electrical connections.
