2. The FG3 needs a constant 12-24 volt signal at the BAT+ and BAT- terminals
when the vehicle is on and 0 volts when the vehicle is off.
Note
If the ignition wire is not connected, the FG3 will not function
properly. If the wire is connected, and the FG3 is functioning
properly, the FG3 will go into Sleep mode after turning off the

5.2 Connect the Data Interface to the FG3
The instructions for this procedure depend on the type of vehicle
– whether it is a
heavy duty vehicle or a light duty vehicle. Light duty vehicles have an OBD II
connector for electronic instrumentation, while heavy duty vehicles have an SAE
J1939 connector. The following sections provide instructions for both types of
vehicles. To view the connectors’ pin out information, refer to Appendix B – CAN
Bus Data Connectors on page 38.
