Where do you find the on-board diagnostics for a 2000 Honda Odyssey and where can picture of port?

The OBD-II diagnostic port on a 2000 Honda Odyssey is located under the dashboard, on the driver's side. It's usually near the steering column, often tucked away and might require a flashlight to locate. It's a 16-pin rectangular connector.

Unfortunately, I can't display pictures directly. However, if you search Google Images for "2000 Honda Odyssey OBD-II port" or "Honda OBD-II connector location," you'll find plenty of pictures showing exactly where it is. Many automotive repair sites and forums will have images illustrating the port's location in various Honda models from that era.
