ok, i've been trying to find one of these for the longest time. i just got the part number if anyone else is interested. it's the oem interior light kit 4 stage switch. 1st push, the footwell lights come on. 2nd push the cupholders come on. 3rd push they both go on. 4th push, they both go off. i did my own interior lights but i just couldn't find the damn switch to go with it. the part number is: pts21-21050-sk. should be available from any toyota parts store. the part may be on back order so it'll take about a week. the cost is around $25.
