Where is the 1991 Honda Accord OBD port location?

I’m trying to help my friend with some repair diagnostics on their car but it’s really old. Can you tell me where to find the OBD port location on a 1991 Honda Accord?

Helping your friend with car repairs is very noble, but it may not be as easy as you think on a car this old. The OBD-II scanner that we use today wasn’t standardized on cars until 1996, so the fact of the matter is that you won’t find any OBD port location on a 1991 Honda Accord.
There’s one other way to read diagnostic codes in a 1991 Accord, but it’s not nearly as easy as an OBD-II scanner. It involves connecting a jumper to a diagnostic connecter in the passenger side kick panel and then counting the number of times the Check Engine Light flashes after starting the car.
Unless you’re well-versed in classic car technology, your friend is probably better off taking their car to a mechanic. A seasoned professional will be able to accurately diagnose their car problems and tell them whether or not they’re worth fixing.
Once you’ve figured out what’s going on with your friend’s 1991 Accord, it will be more important than ever to keep up with a regular car maintenance schedule. It’s a miracle that it’s lasted this long—but keeping it properly maintained will be essential to get a few more years out of it!
