I recently purchased a 2016 Four Winds 35sd super c Ford 550 with 6.7litre diesel. The unit was not optioned with and exhaust brake but it was available on the truck and has a blank in the dash for the switch. Has anyone had a Ford dealer activate the brake feature or add an after market brake?
My 18 came with the engine brake...there's a good chance yours may have it...all you may need is to add a switch and programming. My buttons are top center on the dash, just over the Navigation screen.
