Choosing trailer electrical connectors

Start with the connector on your vehicle and the one on your trailer, then compare pin layout, shape and whether you need a plug, socket or adaptor.

Know both ends

Check the connector already fitted to the vehicle and to the trailer. Where they differ, an adaptor between the two layouts may be the practical choice.

Flat or round, small or large

Flat and round connectors suit different setups, and pin counts vary. Confirm the pin count your equipment uses rather than assuming one style fits both.

Plug, socket and housing

Plugs and sockets are the male and female halves of a link. Consider housing material and terminal type, especially for connectors exposed to weather.
