Question:
I have a 2023 Mercedes Sprinter beast mode. Storyteller. I saw a video online a guy doing install for the trailer brake controller with a link to your website. The problem I’m having is I can’t seem to find the plug-in play set up on your website and I don’t wanna be slicing any wires. You could send me the links so I can put the order together that would be perfect. Thank you so much.

Hey Steven, thanks for reaching out. If you want to add a brake controller to your 2023 Sprinter 2500 without doing any cutting or splicing, the best option for that is the following:
- Redarc Tow-Pro Link Bluetooth Brake Controller - Off-Road Mode - 4 Axles - Proportional # RED57AR
This plugs in directly behind your 7-way at the back of the vehicle. No cutting or splicing required. The main module mounts behind the bumper, then you have a Bluetooth remote you can put in the cab, or you can control it with the Redarc smartphone app.
There are under-dash controllers you can use too like the Redarc Tow-Pro Elite # RED44FR you were looking at, but this does require splicing since you have to hardwire the controller. There are no plug-in options for an under dash controller at this time, so in my opinion, that Tow-Pro Link is definitely the way to go.
Does your sprinter have a factory 7-way? What trailer will you be hauling?

I have about 10,000 trailering miles using the Redarc Tow-Pro Link Bluetooth Brake Controller. It was very simple to install and even easier to use day to day. Once you set the brake gain, you don’t even have to think about it. It simply works every time. Highly recommend.

Yes it has a factory 7 way. I have the green plug under my drivers seat. I watched a guy do an install on YouTube. He plugged into the green plus under the seat.
