Hello I have a 2015 G series Bennington , I bought it use only 70 Hrs . The person I bought it from did not know much about it or even how things worked lol ,. So I got most of it , Except I have two Rocker switches on the starboard dont do anything , They do light up that is all . I would like to add lights to those switches . But not a electrician where can i see how to add the pos and neg wires from the new lights I want to install . ? or is there a way I can find what they might be controlling , if anything . Thanks
