4-Way & 5-Way Trailer Wiring Connectors

Find 4-way and 5-way trailer wiring connectors for compatible light-duty and recreational towing applications. Four-way flat connectors are commonly used for basic trailer lighting functions, while additional connector configurations can support extra circuits depending on the trailer and tow vehicle.

Before ordering, compare the connector style, number of circuits, wiring configuration, and vehicle or trailer requirements with your existing towing setup.

6-Way & 7-Way Trailer Plugs & Sockets

Shop 6-way and 7-way trailer plugs, sockets, connectors, and replacement components for trailers requiring additional electrical circuits. Depending on the towing setup, these connections may support functions such as trailer lighting, electric brakes, auxiliary power, and other compatible electrical equipment.

Connector appearance alone does not guarantee identical wiring. Always confirm the required pin configuration and wiring functions before installation.

Trailer Wiring Harnesses & Adapters

Find trailer wiring harnesses, vehicle-specific harnesses, adapters, extensions, pigtails, and replacement wiring assemblies for connecting compatible trailers and tow vehicles.

Adapters can help connect tow vehicles and trailers equipped with different connector styles, provided the required electrical circuits and functions are supported by both systems.

Trailer Junction Boxes, Plugs & Electrical Connections

Shop trailer junction boxes, replacement plugs, sockets, terminals, connectors, and wiring accessories for repairing or maintaining trailer electrical systems. Junction boxes can provide an organized connection point between the trailer plug cable and individual trailer circuits.

Choosing the Correct Trailer Wiring & Connector

Before ordering, verify the connector type, number of pins or circuits, wiring configuration, voltage, tow vehicle application, trailer requirements, and manufacturer compatibility information.

When replacing an existing connector, confirm the function of each circuit rather than relying solely on wire colour. Wiring configurations can vary between vehicles, trailers, connectors, and previous installations.
