Hello Adam, thanks for reaching out. Your best option for this is the Hayes Air Actuated Trailer Brake Controller # HA100400C. This will allow you to tow an electric brake camper with an air brake equipped semi like your Peterbilt. I have included a diagram for you below. You will also find the manufacturer instruction manual, as well as an install video linked below.

Hey Adam, how did things go with the Hayes air actuated brake controller on your Peterbilt? Did the wiring diagram and instructions make the setup clear? Your feedback could really help others working with air brake trucks and electric brake trailers.
