This.

I fished an old Lenovo Thinkpad out of an E-waste bin, tossed in a 1TB hard drive, bought a cable and downloaded a totally legal copy of Techstream. Now I can mess around with vehicle settings. Unfortunately there isn't a whole lot you can adjust with the Yaris but there are a handful of things, one being that seat belt light.
