Hi Troy,
There are no plug-and-play brake controllers for your Freightliner M2, so you'll have to hardwire everything in. The first thing you'll need is a 4-way, the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236, followed by the Universal Installation Kit for Trailer Brake Controller # ETBC7.
You will first install the 4-flat, which will activate your trailer's lighting functions, and you'll then plug that into the 7-way that comes with the # ETBC7, which also gives you the wiring, circuit breakers, and rest of the hardware needed for installation.
With that you can install a brake controller, with the best option being the user-friendly, highly reliable Prodigy P3 Brake Controller # 90195.
