This is just about the same as your truck but it doesn't have the little switch in it. It might be an after market thing previous owner installed. Have someone look around at the outside of the truck when you turn it on and off and see if anything lightens up or happens. Heated mirrors maybe. It's not a diesel is it? I was thinking maybe glow plug switch. See if the dealer has any info about it

It is not a diesel and I don’t notice anything when I switch it on. I asked the dealer when I bought it and they said they didn’t knowThis is just about the same as your truck but it doesn't have the little switch in it.

On most Fords nowadays the heated mirrors only come on with the rear defogger .Dont know of any glow plug switch ever been fitted in that vehicleThis is just about the same as your truck but it doesn't have the little switch in it.

Fog lights maybe (may not have noticed if you tried the switch in the middle of the day)?
Is it not possible to get in contact with previous owner and ask them ?
Look to the lower left side. There is a second switch, on that same box. It's hard to see, but the image stamp above, looks like a Automatic lights On, and below it Auto lights Off. The button by itself could control Auto Lamp System active On/Off ? Or if equipped a lesser chance, it might be Fog Lamps Control?View attachment 56754
Does anyone know what this switch does? I just purchased this truck and I cannot find anything online about it. When it is switched in to the ON position the light turns on and doesn’t turn off even when the vehicle is off and the keys are pulled
