I have a 2008 Aruba Lite by Starcraft and I have 2 questions. There is a switch under the sink in my galley that I don't know what it is. I haven't been able to get ahold of the "right person" at my dealer yet but the wiring goes into the floor & unless there are 2 water pumps on it, I'm wondering if, because I have an Artic package on it, that maybe it has heated pads on the tanks. There is a seperate switch on the gage panel that says pump so I'm thinking this is the water pump for when I'm pumping out of my fresh water tank. Any one have any ideas what the other switch would be?
