Factory Brake Controller Wiring Harness Location on a 2015 Mercedes Sprinter Motorhome

Question

Question:

I have a 2015 Mercedes Sprinter Motorhome. It came with a 7- way plug and trailer hitch so I thought it has a trailer pak. I cannot find the wire connection under the seat. Could it be some where else on this mod? I Have a Prodigy P2 I purchased from you I need to install.

If Mercedes installed the factory brake controller harness on your 2015 Mercedes Sprinter Motorhome, it would be under the driver's seat. It would have a green connector. If the harness is not under the seat, then from our experience, it was not included on the vehicle and a brake controller must be hard wired.

One way you could try to verify if your motorhome came with the brake controller harness would be to provide your VIN to either a Mercedes dealer or to your RV dealer.

If the harness is not there, then I recommend using our brake controller wiring kit, # 5506, to complete the installation of your brake controller. I have attached a few help articles on brake controller installation for you to check out. If you have any questions, feel free to let me know.
