from memory, the IS's have the rear fogs switch there, and then something else aswell.
and with the altezzas, don't think they have anything there..
my one, a RS manual as well, has the coin holder, then the other 2 holes have the plastic covers on them.. some ppl have the security flashy light mounted on one of the plastic covers
so yea, don't think the RS's have any switches there :)
