Brake Controller Recommendation for 2021 Jeep Grand Cherokee with Tow Package
Updated 01/05/2026 | Published 09/23/2024
Question:
Greetings: I have a 2021 Jeep Grand Cherokee Trailhawk that has the towing package. It does not have a trailer brake controller but has the quick connect plug mounted under the dash above the parking brake. I want to put in a trailer brake controller TBC. I want to mount the TBC control unit with velcro to the lower dash right of the steering wheel. I will be towing a single axle 2-3000 lb. trailer with 10 electric brakes. What would be the best TBC for this application, mounting and what parts would be needed? Thanks for the help. Rob

Hey Rob, for your 2021 Jeep Grand Cherokee I would recommend the Prodigy P3 part # TK28ER which comes with a custom fit harness designed for your Grand Cherokee. The P3 is the nicest controller around due to how easy it is to use and setup and how well it performs so it's a really great option.

Hey Rob, how did the Prodigy P3 work out on your Grand Cherokee when towing your trailer? It’s a solid choice for smooth braking, so I’m curious how the setup went. Sharing your results could help others with a similar Jeep and towing setup.
