Thanks for the photo of your Prodigy P3 # 90195. That will work well for your application. You will also need a wiring harness that can handle multiplex systems like the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT and then the Brake Controller wiring kit # ETBC7. This wiring harness will capture the light functions needed and then the brake controller wiring kit will give you the 7-way and circuit breakers you need to give you the other electric brake trailer wiring connections. This won't alter your truck's wiring at all other than grabbing a brake light signal and adding reverse if desired. With the brake light signal and the internal accelerometer you will have trailer braking proportional to your truck braking for a smooth ride.
