In most cases no. Most vehicles have a standard OBD connector. This connector is usually located just under the steering wheel. Datablaze will provide a GPS tracking device that plugs directly into the OBD connector of your vehicles. If by choice, or because your vehicle does not have a compatible OBD connector, Datablaze does have an option to supply hardwired GPS tracking devices. In this case these usually will require some experience to know how to wire them to your vehicles.
