2.2 Locate the OBD-II Connector in your vehicle
As noted, this is typically the most dangerous aspect of OT-1 installation. A safety helmet is
wholly optional, but a flashlight can be extremely helpful. The connector is required to be within
3’ of the driver’s seat in the vehicle and accessible without tools. Generally it is somewhere just
behind the bottom edge of the dashboard, immediately in front of the driver, but it may be in a
relatively obscure place, like hidden behind an ashtray.
If you are unable to locate the connector by inspection your best bet would be to either ask a
mechanic familiar with the make and model vehicle or locate an online hobbyist/enthusiast group
devoted to your vehicle.
Here is a sample OBD-II connector. Please note
that the orientation of the connector varies from
vehicle to vehicle.
For example, in this example, the wide part of the
connector is ‘down’. In other installations this
wide part of the connector will be up. In still
other installations the entire connector may be
‘facing’ the floorboard.
On many newer vehicles the connector is
concealed behind a small door or removable
plastic cover plate.
Also, the connector itself may be covered with a
small, removable, rubber cap.
Although it is not required, once you have located your OBD-II connector you might want to note
which pin positions are populated (you can usually look into the face of the connector and see
which pin positions contain metal contacts). This can be useful in determining what OBD-II
protocols your vehicle supports and is extremely helpful if you need to contact us with a
connectivity or compatibility problem. Looking into the face of the connector the OBD-II pins are
numbered as follows:
