Parts Needed to Install Brake Controller on 2019 Mercedes-Benz Sprinter 2500 With 7-Way


Hi I need to add wiring and brake controller for my 19 sprinter. Truck has wiring for trailer lights 7 pin connection but missing wiring for trailer electric breaks. Which kit should I buy to make it the easiest to install ?


Expert Reply:

Since your 2019 Mercedes-Benz Sprinter 2500 has the factory 7-way, that means you'll have the factory tow package, so I assume by "wiring" you are referring to the wiring adapter needed to plug into the brake controller (it will plug into the green port under your driver's seat as in the accompanying photo).

The correct part for your '19 Sprinter 2500 is the Tekonsha Custom Wiring Adapter # 3063-P.

Then for a brake controller that works with that adapter, there are a couple options I recommend checking out, starting with the best value, which is the Brake EVN # TK63VR.

The Brake EVN is a great value due to its unique combination of quality and cost-effectiveness. It gives you smooth braking, is easy to use, and has a bright display that is simple to read and understand. For a combination of quality, reliability, and price, there really isn't a better option than the I-Command.

For a premium option I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195.

The P3 gives you the most consistently smooth braking, has a bright LCD screen that is easy to read, lets you store settings if you have numerous trailers, and has continual diagnostic checks with safeguards to prevent battery drain or shorts. This is a very high-performing and reliable controller that has been reviewed thousands of times by our customers and has a nearly perfect 5-star rating, which speaks to its quality.

I have added links below to video reviews for you to check out.
