On the Honda Ridgeline, the DLC (Data Link Connector) — also known as the OBD-II port — is typically located under the dashboard on the driver’s side.
Look just below the steering column, near where your knees would be when seated. It's often tucked just above the pedals or slightly to the left, mounted horizontally. You shouldn't need to remove any panels to access it.
Feel free to reach out to us with more details on your Ridgeline you can't find it — location may vary slightly across generations.
