I have a 2004 GMC Sierra, im not terribly familiar with trailer brake systems and such but im pulling an older open aluminum trailex dual axle, and im told i need a brake controller installed in the truck to manage the system. I have seen controllers avaiable on ebay in the $30-$100 range. Do you guys recommend any particular controller, and can i do the install/wiring myself fairly easily?
