I have only had my Prado for about a month or so and noticed this switch, the previous owner didn't know what it did either.

This is the picture from behind:

So it is connected.
The wires run along the back of the engine bay and the yellow wire is connected to the headlight, the brown wire goes to a little black box which then connects to the battery:


I checked today if the switch did anything and it appears that it doesnt do anything.
Any ideas?
