Side of sink cabinet switch?

I have a 97 Itasca Sunrise 32RQ there is a switch on the couch side of the sink cabinet. I cant find out what the switch operates? There are 3 purlple wires going to it so it must be something on the 12v side. Any clues?

Try a 12V test light or volt meter on the wire terminals before and after the switch. Power to switch? Switch controlling power to other side?

We had a 97 Adventurer and it was our first ever RV. We read and reread the books that came with the coach but we could not figure out what the unmarked switch was on the dinette side. We were afraid to touch it in case we might do something "BAD". Come to find out it was a light switch for the lights at the base of the floor. Only a possibility and if they are burned out you would not be able to tell.

I also think it's for the aisle lights.

In my previous rig the swith below the counter top by the sink was for the water heater.

Here are the Body, Wiring Diagram and Body, Wiring Installation diagrams for your coach. Here is the Wiring Identification Guide . You'll notice that Winnebago labels every 12V wire every few inches, and you can look up those labels in the identification guide.

3 wires would imply a 3-way switch, paired with at least one other switch for the same function. Pages 3 and 4 of the Body wiring diagram show 2 three way switches for the Courtesy Lamps (footlights), each with 3 purple wires, labeled NU, PH, and NY on one switch and NU, JE, and NY on the other. You should also be able to look at the Body wiring installation diagram to identify where switches, etc. are located.
