This is a new Toyota accessory kit for Yaris - it is a whole kit that lights up your lower dash foot area blue.
It was on display so have whole kit but no box.
If you have a HATCHBACK it is plug and play. If you have a SEDAN, it is plug and play but you have to put the switch in a different spot inside the armrest console or under the dash - the hatchback model has a spot on the center console trim pre-made for the switch where sedan does not.
