Nope - everything everyone has mentioned is not for that switch. I'm agreeing with Starcraft that it's a dummy switch. I'm going to leave it on and see if there's anything that lights up somewhere - but I doubt it. Unfortunately the plate is not screwed in so I can't remove it and check to see if it is wired into anything.
It's really disappointing in that there is no manual / schematic specific to this model. The only manual that's available says "Starcraft Launch Travel Trailers 2015". And that covers a lot including tent models, etc. Poor documentation to say the least. (and by the way - I'm the type of guy who this will drive insane until I figure it out)
