Typical Ignition Detection
The white wire is used for ignition detection. It is strongly recommended to connect this
wire to ignition key “RUN” position as shown up.
An alternative to connecting to the ignition switch is to find a non permanent power source
that is only available when the vehicle is running. For example the power source for the
FM radio.
Ignition signal can be configured to start transmitting information to backend server when
ignition is on; and enter power saving mode when ignition is off.
