dashboard switch

[Knickers]

Can anyone tell me what this switch location is for on my D22. It is blanked out, but does have wiring attached at the back.
could it be for fog lights on other models? It would be good to use existing switch locations and wiring when i install spotties.

That blank is usually where the Diesel hand accelerator goes ,much like a manual choke on early petrol cars.
