Please look at the bottom left corner of your steering wheel and the port should be around that location or on the bottom part of your dashboard. This would be around where your car's fuse box is located. You'll be able to plug in your obd widget at that port. Otherwise, you can get help at your local autozone to find the port location.

The norm states that the port must be located inside the vehicle passenger compartment. Depending on the make and model, it may or may not be easy to locate. ...
The OBD-II port is usually located under the dashboard, beneath the steering wheel column (1 - 3 in the diagram below). If not located beneath the steering column, look for the port in the areas indicated by numbers 4 - 9. https://www.verizonwireless.com/support/knowledge-base-210135/
Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line.
The high pressure port is much larger than the low pressure port. It is impossible to hook a charging hose to the wrong port. If the charging hose is leaking, it is either because it is not clicked all the way on the port or the charging hose connector is defective.
The high pressure port is located on the discharge hose just to the rear (driver's side) of the A/C compressor.
The easiest way to locate the low side charge port on any vehicle is to locate the A/C compressor, follow the "larger" of the two lines all the way back to the firewall. Some where along that line you will find the low side charge port.
Good luck.
Regards,
mcdevito75 here, The low side port of your A/C is located on one of the shiny metal lines comeing out of the firewall, they are attached to the evaporator under the dash, from the firewall carefully follow these silver lines till you reach the charge port. The port may be covered with a brass looking cap, un srew the capp and the port looks like the valve on the tire.
