Looking For Brake Controller For 2024 Mercedes Bens Sprinter 3500 RWD

Question:
Hello, I am looking for a trailer brake controller for my 2024 Sprinter RWD 3500. Ideally with a manual over-ride slider but that is not an absolute requirement. Also hoping you have any wiring harnesses I will need. Thank you so much

Hello Kent, thanks for reaching out. Do you already have a 7-way plug on the back of your sprinter? If not, you can use the Tekonsha OEM Replacement Vehicle Wiring Harness # TK82VR to add one. This kit includes everything you need to add a 7-way including all of the wires for a brake controller.
For the controller what I recommend is the Tekonsha P3 # 90195. It has a manual override slider on the bottom which is definitely something you will want to have. Overall it is just our most reliable well-reviewed controller so it comes highly recommended.
I hope this helps. Leave a reply below with any other questions or comments and I will get back to you.
