Default Brake Controller Installation

Howdy Everybody! I have a 2007 Sierra 1500 extended cab with a factory hitch and towing package. It has a 7 pin plug but no brake controller and the battery charging circuit needs to be energized. Is it better to have a GMC dealer install the controller and hook up the charging circuit or the TM dealer? Thanks in advance.
