Where is the OBD interface located on the Focus?

The OBD interface of the Focus is located in the storage compartment below the light control switch. Below is detailed information about the OBD interface: 1. The OBD interface is generally used to communicate with the vehicle's electrical systems, such as the onboard computer. 2. The new Focus uses a CAN bus system, and all electrical systems connected to the CAN network can be read and modified through the OBD interface. 3. The OBD system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it will immediately issue a warning. 4. After the vehicle is turned off, the OBD system will automatically enter a dormant state.
I've been researching Ford models for several years, and the OBD port location on the Focus is actually quite fixed. When you're sitting in the driver's seat, push the steering wheel all the way back and look down at the lower edge of the instrument panel, about 15 centimeters above the brake pedal. The port is a black trapezoidal 16-pin socket, usually hidden behind a plastic cover. Many beginners tend to search randomly on the passenger side, but in fact, it's always on the left side of the driver's position. I've seen people dismantle the center console to find the port, which is a waste of effort—you can usually feel it by reaching your fingers below the steering column. Remember to turn off the engine before connecting the diagnostic tool, as excessive force when plugging or unplugging can damage the clips. Some car owners who modify their audio systems use this port for power, but leaving the wiring harness hanging for long periods can cause looseness, so it's best to secure it properly.
