4.3.2 DLC location

For passenger cars, the DLC (Data Link Connector) is typically a standard 16-pin connector where diagnostic code
readers interface with the vehicle's on-board computer. The DLC is usually located 12 inches from the center of the
instrument panel (dash), under or around the driver's side for most vehicles. If DLC is not located under dashboard,
a label should be there telling location. For some Asian and European vehicles, the DLC is located behind the
ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the
vehicle's service manual for the location.
For commercial vehicles, the DLC is always located in driver's cab.

4.3.3 Vehicle connection (For Passenger Vehicle Configuration)

The method used to connect the VCI device to a vehicle's DLC depends on the vehicle's configuration as follows:
 A vehicle equipped with an OBD II management system supplies both communication and 12V power through a
standardized DLC.
 A vehicle not equipped with an OBD II management system supplies communication through a DLC connection,
and in some cases supplies 12V power through the cigarette lighter receptacle or a connection to the vehicle
battery.
For OBD II vehicles, connect the SmartLink C to vehicle's DLC directly via the OBD II extension cable.
For non-OBDII vehicles, proceed as follows:
*Note: If the power supply on vehicle diagnostic socket is insufficient or the power pin is damaged, you can get power via
either of the following ways:
A. Via Battery clamps cable (optional): Connect one end of the battery clamps cable to the power jack of the OBD I adaptor
box, and the other end to the vehicle's battery.
