Fusebox question

I know what goes in the top two slots in the right hand corner but does anyone know what goes in slot 30?

Nothing in any nova ive come across, its probably for the option of front fogs or electric mirror or the heated seats, or indeed any of the optional extras that we never saw in this country lol



*Random edit, thats my fusebox* lol

I've got wires in mine, presumably for the alarm system.
