Thanks for reaching out, Gary!
It sounds like you're needing the Hayes Air Actuated Trailer Brake Controller # HA100400C and either the Trailer Wiring 7-Way Upgrade Kit # ET7WK or the vehicle side Universal Wiring Kit # ETBC7.

Hey Gary, how did things go with the Hayes air actuated brake controller and the wiring kit for your Freightliner? Your update could make it easier for others setting up electric brakes on similar trailers.
