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