Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road.

      Hello Migelle, yes this wiring kit uses quick splice wire connectors. Just insert wires and snap shut to create a permanent connection without using solder. The picture on the box shows what could be accomplished with the Wiring T-Connectors.
