3.1 Preparation
y Turn on the vehicle power supply.
y Throttle should be closed at its close position.
3.2 DLC location
The DLC (Data Link Connector or Diagnostic 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 t he driver’s side for
most vehicles. If Data Link Connector 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.

3.3 Vehicle connection
The method used to connect the diagnostic connector to a vehicle’s DLC depends on the vehicle’s
configuration as follows:
y A vehicle equipped with an OBD II management system supplies both communication and 12V power
through a standardized DLC.
y 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.
Follow the steps mentioned below to connect OBD II vehicle
1. Locate vehicle’s DLC socket.
2. Plug the diagnostic connector into the vehicle’s DLC socket (It is suggested to use the OBD II
extension cable to connect the diagnostic connector and DLC socket.).

For non-OBDII vehicle, proceed as follows:
1. Locate vehicle’s DLC socket.
2. Select the corresponding non-16pin connector.
3. Plug the non-16pin end of the connector into the DLC socket, then connect the other end to the OBD I
adaptor, and then tighten the captive screws.
4. Connect the other end of the adaptor to the included diagnostic connector.
5. To supply power to OBD I adaptor from:
A. Cigarette Lighter
receptacle, and the other end to the power jack of OBD I adaptor.
B. Battery Clamps Cable:
other end to the power jack of OBD I adaptor.
: Connect one end of the cigarette lighter cable to vehicle’s cigarette lighter
