Abstract: A combined four way and seven way connector assembly for communicating a towing vehicle's electrical system with either a four way or seven way input harness associated with a towed vehicle. The towing vehicle includes a wire harness supplying an output of the electrical system. The connector assembly provides a three dimensional housing including a top and a plurality of interconnected sides and which is secured to a suitable rear end location of the towing vehicle. A circuit board, or other suitable component, contains a plurality of electrical circuits and is secured within the housing. A first plurality of terminals defines a four way connector and a second plurality of terminals defines a seven way connector. Each of the first and second pluralities of terminals communicates with a selected number of said plurality of circuits and further define first and second input plugs accessible through the housing by the towed vehicle input harness.
