SinoTrack ST-902A Plug-and-Play OBD-II GPS Tracker for Cars
SinoTrack ST-902A OBD GPS Tracker is a plug-and-play GPS tracker for compatible cars with a standard 16-pin OBD-II port. Simply connect the tracker to the vehicle’s OBD-II socket—there is no wiring to cut and no separate wiring harness required for standard installation. This makes it a convenient choice for drivers who want vehicle GPS tracking without a complex installation.
After connecting the tracker, a compatible SIM card and the required network and platform settings are needed for tracking. Use the SinoTrack PRO app or web platform to view location information and supported alerts. The OBD-II port powers the tracker, while its built-in backup battery provides temporary power if the tracker is disconnected from the port.
Plug the SinoTrack ST-902A into a compatible 16-pin OBD-II port for a no-wiring setup. No cutting vehicle wires or separate wiring harness is needed for standard use.

Important OBD-II Information
