I just picked up a 2016 6.7 c&c and I seen some of these come with a controller to turn on and off the exhaust brake right next to the 12v power source on the driver side. My question is, is the wiring already there so if I bought the switch I could just plug it in? Already missing having one and I dont even have 1k miles on the truck yet,thanks in advance.
