I purchased a used Northtrail 33BKSS travel trailer. I cannot find what the switch is for. I also don’t know what goes beneath the switch. I’m hoping somebody has the same model or would know what that switch is for. I thought it was for lighting underneath the island but I haven’t seen it. I took the panel off underneath the sink to trace the wiring. But I noticed the wires are disconnected and there is nothing there does anyone know what these are for?
