I have a 2007 GS Independence 8327, on the left cabinet coming in the coach I have 2 white switches, one turns on the overhead lights above the stove and table area and I have no idea what the other one does. It has power to it and the wires are grey, I tried tried tracing them behind the stove and fridge and the harness drops down behind the heater and I can’t trace it any further, does anyone know what this might be for?
Any help is appreciated

Thanks Torch
