OBDWhat does an OBD port look like?
The port is a trapezoid-shaped socket with two rows of pins. On trucks it is usually behind a cover; on cars it is mostly above the driver footwell.
- Plug in the device with the ignition off, then switch the ignition on.
- If you cannot see the port, use a torch; it is often mounted on the underside of the panel, facing down.
- Do not force covers; they open with a latch or clips.
