This hard wire kit is designed to fit the iTrack Mini GPS Tracker (TK102). Simply connect the 2 wires to your external power source such as a car battery and the tracker will have a constant power supply. No more worrying about the battery life of the tracker! Please note, you should leave the battery inside the tracker as this will act as a back up power supply in the event of power loss.
