Well if it's anything like my jeep wind deflectors. the go on the trim that is around the window. For the mr2, it will be the black trim around the door opening. The front of the deflectors ussually slides underneath the side view mirror mount. If the deflectors have double sided tape, you must scuff the black window trim with some fine grit sandpaper, then clean the area with rubbing alcohol. Then you can stick the deflectors on.
