2009 Suburban Integrated Trailer Brake Controller

I just bought a new 2014 28 International Serenity and will be using my 2009 Suburban 2500 as the TV. It has an integrated trailer brake controller. Is this compatible with AS brakes? According to the manual, a dealer has to connect the wires for the battery feed and trailer brake pins in the hitch since I have not towed with it before.



Any suggestions would be much appreciated.



Thanks!
