How do I find the plug to connect the ScanGauge?

The OBD2 connector is supposed to be located within 1 meter of the steering column. It is usually under the dash and just to the right or left of the steering column. Sometimes it will have a cover over its face. Other locations are under the dash on the passenger side under the dash, behind the ash tray and in a rare case, under the ash tray in the back seat armrest. The pictures below show the OBD2 plug in a typical location.
