I used them on several different types of vehicles years ago when I worked for a stereo shop. They work, but are typically a little slow (the windows). I actually have a set of OEM 4-door Sidekick locks and power windows for a VERY reasonable price if you are looking for original Suzuki parts.
BTW, that Tracker looks WiLd!
