OBDLink MX Wi-Fi Setup

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 4: Plug MX Wi-Fi into the diagnostic link connector (DLC)

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.

Step 5: Turn ignition key to Key On, Engine Off 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.
