Engine Preheat Switch

On to the left, off to the right on my 93. There is a pump, I think it is
twelve volts that is behind my house battery trays. It circulates warm hot
water / antifrezze mix to the engine and I think the hot water heater from you
Primus or Webasto unit. I found mine this summer when I turned on the switch
and heard it.

On my 91 on the far left topmost driver overhead dash panel, there is a black
two position toggle switch labeled "Engine Preheat" - that's it, no "on" or
"off" indication, no light. My question is: Is "on" when the switch is toggled
in to the left side or the right side of the switch? What kind of electrical
draw should I see on any of the gauges when it is on - *if* it is working?
