The 2017 Mercedes-Benz Sprinter 3500 dually 170 wheel base will require a few items to install a brake controller. I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 for a brake controller that will give you the proportional braking to keep your trailer brake timing and intensity in line with your vehicle.

To wire this, you will first need a 4-way connection. If you don't have one, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118649. I've attached a video of this installation to assist. Then you want the Universal Installation Kit for Trailer Brake Controller # ETBC7 to give you the additional wiring, connectors, and circuit breakers needed to complete the installation. These components will ultimately give you the 7-way trailer connection with trailer brake function for your trailer. I've attached a video of this installation on a 2016 model to assist.
