I have a 12v switch marked AUX on the dash of my 02 Tradewinds. It's definitely OE but I can't determine what it controls. It's adjacent to Map Light, Stereo Power, etc. Any ideas?

Could be your Battery Boost switch,
In a motorhome the batteries are separated by a circuit to prevent the House batteries from draining the Chassis battery and thereby leaving you unable to start the engine. Most motorhomes have a bypass switch that allows you to start the engine with the House Batteries if the Chassis battery is low. This is generally called the Battery Boost switch.

I have two rows of five switches on the left side of my dash panel.
The right hand switch on the top row is marked "AUX" and has nothing wired to it. There is 12 volts to the switch but no wire to the output terminal.

Mine is on the right side, under the stereo. Definitely not battery boost, that's on my left. It has power in and power out, just can't find what it controls. We've had the rig for a year and don't miss what it may control, but thought I'd ask.

It is for dealer added accessories, per the owners manual.

Mine has wires to it and they where power, ground, switch light inside the button when headlights where on and a light that comes on when the switch is in the on position. However, hidden from the view from above, was one leg on the bottom of the switch had no wires connected to it. This was the power out to connect to what ever you want. I connected a triple 12V socket and mounted it under the dash, and plugged my Garmin GPS and Sirrius Sat radio to it, turning them on/off with the AUX switch. Both my 05 and 08 Dolphins came like this with nothing connected to the 12V output pin of the AUX switch.

as stated ,they are for adding on something later. I added a 12 volt plug for my Garmin and used one of the aux switches for power.

If the switch is momentary then I would say it is a battery boost switch to start the engine with the house batteries. If it isn't momentary then it is probably for the dealer to wire auxiliary power to a dealer installed option.
