Installing OBDLink in your vehicle

Step 1: Locate the OBD-II diagnostic connector in your vehicle

The diagnostic connector is always located in or near the interior dashboard of your vehicle.  The diagnostic connector will usually be exposed, but sometimes it’s hidden under a decorative plastic cover, or behind an ashtray or coin tray. The most common location is below the steering column, just below the driver’s dash area.



Step 2: Turn ignition key to the ‘ON’ position

On some vehicles the ‘ON’ position is marked with the Roman numeral ‘II’. If there are no markings, turn the key clockwise and stop just short of starting the engine.

Step 3: Plug OBDLink into your diagnostic connector

Don’t use excessive force, but make sure it fits snugly.


OBDLink MX Bluetooth is used in the above video, but the process is the same for all OBDLink devices.

Once plugged in, the ‘Power’ LED will turn solid green.

For Bluetooth models, the ‘BT’ light will flash slowly. For Wi-Fi models, the ‘Wi-Fi’ light will flash slowly.

If all LEDs are off, check the cigarette lighter/auxiliary power port fuse.
