How do I connect the Innova 3011 OBD2 Code Reader to my vehicle?

Turn off the ignition and locate the 16-pin Data Link Connector (DLC) in your vehicle, then plug in the Code Reader’s cable connector. Ensure it is correctly connected as the cable is keyed and will only fit one way. Turn the ignition back on but don't start the engine—let the Code Reader automatically link to the vehicle's computer system.
