Power through trailer hitch systems and methods

A trailer hitch system of the present disclosure includes a power through ball hitch and a power through trailer coupler equipped with electronic connectors such that an electric connection between a tow vehicle and a trailer is automatically made when the trailer coupler is attached to the ball hitch. The trailer hitch system may further include a power through hitch receiver (e.g., for bumper pull hitch systems) whereby an electrical connection is made between the hitch receiver and the ball hitch automatically when the ball hitch is installed in the hitch receiver.
