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. An electrical supply of the towing vehicle is engaged, via a wire harness or input connector, through the housing and with the circuits and in order to electrically communicating the towing vehicle'"'"'s electrical supply.
