I have a 2015 2500 ram I hook my 2016 cougar 5th wheel up and get intermittent trailer disconnect message. RV shop has been through the trailer replaced plug assembly on truck and trailer. Also has been through the trailer from plug to breaks no problems. Had the truck in the dealer they also say no problems with the truck. Can I put an Independant break controler in and hook it up to the break light switch and run an electric break wire back to the plug and cut the factory blue wire off and hook up the new controler wire sounds simple but it sound to simple am I missing something.
