Since you have a 7-Way in your 2015 Mercedes Sprinter you will only need a few more components to complete a brake controller install on your vehicle.

First let's start with a brake controller. I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

Next, for a wiring kit to install the brake controller and the 7-way adapter you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.

I attached an FAQ on installing brake controllers for you to check out.

To install the brake controller in the 2005 Honda Pilot will require the part # ETBC7. I wish there was a plug and play option for this vehicle but this would be the only route. I did attach an install video that shows this install in a very similar 2003 Honda Pilot.
