1.2.2 VCI Connector 
The VCI connector works as a vehicle communication interface device, which is 
used to connect to the vehicle’s DLC (Data Link Connector) socket via the 
diagnostic cable to read the vehicle data and then send it to the tablet. 
  Note: Remember to remove the VCI connector from the vehicle’s DLC after use.
