Hey Dave, thanks for reaching out!

The Curt Echo Wireless Brake Controller # C51180 will work with both your Mercedes Sprinter and your Tacoma as long as they have an active 12V power pin and stop/turn pins on the 7-Way.

I'm not sure why we have it listed out that way in our fitguide system, but brake controllers are pretty much universal which is the case with this controller.
