appreciate any insights as to this switch. Debate raging on a Facebook chat about the true nature/function, was it original or not, etc. Does anyone know if it's for "dash lights" as many argue, or heater, as others argue, it is original or not, and lastly, wiring diagram to help the original poster fix. I have one in my 41 3/4 ton also, but it has no wires going to it so I have no idea what it's for either.

That switch is for the dash lights on my '46 pickup.

Dash lamps for certain. It is authentic.

The dash lights only come on with the headlights, when the under dash switch is on. The dash lights can be turned off or on when the headlights are on, using that switch.

That appears to be an authentic Ford dash light switch typically seen in earlier vehicles that did not use a rheostat. The Ford wiring diagram for the B-BB 4Cyl 1941 truck shows a rheostat to control the brilliance of the dash lights. There is an owners manual for the trucks they come for sale on ebay and there may be an reprint available. The owners manual shows the lay out of the dash as well as a wiring diagram of the vehicle. Take a close look at the three hole mount of the switch. when the switch is used the center hole is usually small but the rheostat takes a slightly larger hole.
