install is pretty easy. IMO. it should come with like some double sided tape that you put on the scanner and either hte windshield or the rear view mirror, or wherever you want it. from there, you take the wires and run it up to the headliner. run it across the windshield and down the a-pillar. then you'll have 3 wires. you can ground the ground wires to any good ground you want. then the power wire, i'd connect to one of the fuses on the fuse box that gets a constant supply of power. the battery is another option. then for the 3rd wire. i think its yellow. correct me if im wrong. that connects to your alarm. if you don't have an alarm, connect it to something that turns off when the car shuts off. one example of this is the cigarette lighter.
