Hi Shannon; it looks like the 2017 Freightliner Cascadia 125 uses air brakes. Assuming that is correct, you can use the Hayes Air Actuated Trailer Brake Controller # HA100400C. This is specifically designed for air-brake-equipped vehicles so it will be the best option.

Hi Shannon, how did the Hayes air-actuated brake controller work out with your Freightliner and Momentum setup? Knowing how it performed could help others towing heavy fifth wheels with air brakes.
