Is there a way you can give me the location for the diagnostic connector?

Hello,

The diagnostic port is located on the driver side under the instrument panel.
If you look under the dash just left of the steering column you will see the port.

See diagram and picture for a reference.

Please let me know of any questions.
Thank you.
