Where Is The Brake Controller Plug On a 2019 Mercedes-Benz Sprinter 2500

Question

Question:

Is the 3030-p the correct harness to hook up my p3 to a 2019 sprinter 2500 with factory trailer hitch? I have my van on order but wanted to be ready for when it arrives.

Yes, the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3063-P is the correct harness that will allow you to use the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 on your 2019 Mercedes-Benz Sprinter 2500 without splicing.

The plug that the harness will use is located under the driver seat. It is a green four pin plug which can be seen in the attached photo.

to connect the #3063-p is it necessary to remove the driver's seat to get access to the green plug beneath? I can't really see it with the seat in place.

I've not heard of that being necessary. You may need to pull down the factory plug a bit to really gain access to it - sometimes they are actually tapped to a nearby harness.

@ChrisR On my 2017 Sprinter 3500 this plug was tucked under the fuse board directly below the hatch/door on the drivers side seat. It is impossible to see. I found it with a fiber optic inspection camera.

I can definitely say the Draw-Tite #75549 will fit your 2020 Mercedes-Bens 2500. It also looks like the stock exhaust will not need to be modified for the install. I included an install video we did on a 2016 Sprinter for you to take a look at as…

Answer 2

To install a Redarc Tow Pro Elite part #RED63RR on your 2021 Sprinter requires the install harness part #3030-P which at this moment is on back order. For a 2008 Sprinter the correct harness instead is the part #3063-P.
