Where is the 1994 Mazda Miata OBD II port location?
I’ve got an old ‘94 Mazda Miata that I drive in the summer months and when I took it out of the garage today, the check engine light turned on. I want to have it diagnosed but I can’t find where to plug in the code reader.

OBD ports aren’t always in the most obvious places! The 1994
Mazda Miata
OBD port location is in the engine bay—but it’s an OBD I port, not an OBD II port. Pop the hood on your Miata and look toward the driver’s side of the engine bay. You’ll see a small rectangular black box labeled Diagnosis. When you flip open the plastic box you’ll see several pins and a diagram detailing the location of each pin.
The Mazda Miata didn’t become OBD II compliant until the 1996 model year. Miatas that are older than that have an OBD I port, which won’t be compatible with an OBD II code reader. That doesn’t mean you won’t be able to diagnose your car, you’ll just need to use a first-generation OBD code reader instead.
