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.

Yep! The Plug-In Harness # 3063-P mentioned above is the correct part for your 2019 Mercedes Springer 3500 as well.

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.

Answer 1

Switching from a hydraulic braking system to electric on a trailer is actually a lot less complicated than the other way around. You basically just need to lock out your surge brake actuator, swap out your brakes and hubs, and then add some wiring…

Answer 2

As long as your 2019 Mercedes-Benz Sprinter 2500 has a factory plugin connection point for the adapter part #3063-P you will not need to make any modifications to the adapter, it will plug right in into the factory plug and the other end to a…

First you will need to remove the old hydraulic equipment. Remove the surge coupler or actuator, remove all the lines, and finally remove the brake assemblies. If you have 10 inch diameter hub and drums, you may need to replace those as well. If you…

Hey Graham! It looks like the Sunseeker is built on the Sprinter 3500 chassis, I recommend verifying that to be sure. For a brake controller I recommend the Redarc Tow-Pro Liberty #RED24FR. This is simple, reliable, and doesn't take up any space…

Answer 6

You can hard-wire in a brake controller, and it seems that there are not a lot of the Sprinter 3500 models that are pre-wired, at least from what I've seen in my research. I have not seen any reports that this isn't possible, and we even have…

Answer 10

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…

I don't have the color codes, but you should be able to easily determine which wire colors carry which circuits by using a circuit tester like part #PTW2993. Begin with the turn signals and running lights. Have a helper activate the right turn…

Thanks for reaching out! The control knob for the Redarc Tow-Pro Liberty #RED24FR requires both a 1/8" and a 3/8" hole to be drilled one above the other as you can see in the attached photo. The centers of these holes should be 0.3"…
