The screen shot below is from a 2001, but yours is probably the same. The item on the left is your tank monitors - grey, black and fresh water. I would guess that the switch on that panel is for the tank heaters. I am guessing at these - maybe someone else will have better info.
Of course the other items will the vanity light switch and GFCI outlet.
