Order the Harness to go with the Controller to make it a "Plug and Play" install.Also, make sure the Fuse is installed in the Fuse Panel under the hood.....I believe it is a 40 Amp in the "Stud 1" location, this sends constant 12 volt feed to the camper while towing.
*Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"
