Locating the OBD2 port in your 1995 Mazda Miata can sometimes feel like a mini treasure hunt. Unlike modern cars where the diagnostic port is often in plain sight, the first generation (NA) Miata keeps it tucked away. If you’re struggling to find it, or dealing with a loose connector like many Miata owners, this guide is for you. We’ll pinpoint the exact location of the OBD2 port on your 1995 Miata and discuss common mounting issues to ensure your diagnostic scans and inspections go smoothly.
Pinpointing the OBD2 Port in Your NA Miata
For the 1995 Mazda Miata, the OBD2 port is typically found on the passenger side of the car’s interior. You’ll need to look towards the lower right side of the dashboard, near the center console area. Specifically, it’s often positioned to the right of the passenger’s shin area.
To access it, you’ll likely find a small, rectangular plastic cover panel. This panel is designed to be easily removable, often simply popping off with a gentle pull. Once you remove this plastic cover, you should be able to peek behind and locate the OBD2 connector. It might be hanging loose, as described by some Miata owners, or it could be partially mounted.

Many guides and manuals will also mention the area “above the right knee” as a reference point. Thinking of the cigarette lighter as another nearby landmark can also be helpful in narrowing down your search. However, physical location can slightly vary, so always check behind that removable plastic panel first.
Addressing Common Mounting Issues
A frequent concern among NA Miata owners is a loose or improperly mounted OBD2 connector. As highlighted in the original forum post, a loose connector can even cause issues during vehicle inspections. Inspectors may fail a car if the OBD2 port isn’t securely mounted, as it suggests potential wiring issues or tampering.
If you find your 1995 Miata OBD2 port hanging loose, you might want to investigate the factory mounting location. Some owners have found what appear to be broken threaded screw holes molded into the plastic dash panel in the general area. These holes are typically located on the top side of the plastic dash panel, facing towards the front of the car.
However, as some Miata enthusiasts have noted, these screw holes might appear too close together to directly align with the mounting bracket on the OBD2 connector itself. This raises the question of whether there was originally an intermediate mounting piece or bracket between the plastic dash panel and the OBD2 connector.
If you’re trying to remount your OBD2 port securely, consider these steps:
- Inspect for a Missing Bracket: Check if there’s any sign of a missing intermediate mounting bracket. It’s possible this piece was lost or broken over time.
- Examine Screw Hole Condition: Assess the condition of the screw holes. If they are indeed broken, you might need to explore alternative mounting solutions, such as using zip ties or a custom-made bracket, while ensuring you don’t damage the wiring.
- Wiring Length: Be mindful of the wiring length. The OBD2 connector wiring in NA Miatas typically runs towards the center console. This likely means the factory location was intended to be on the passenger side and not further left towards the steering column.
Why a Secure OBD2 Port is Important
Having a securely mounted and easily accessible OBD2 port is crucial for several reasons:
- Vehicle Inspections: As mentioned, some vehicle inspections require a properly mounted OBD2 port.
- Diagnostic Scans: Whether you’re a DIY mechanic or taking your Miata to a professional, a stable OBD2 connection is essential for accurate diagnostic scans to identify and resolve any engine or system issues.
- Scan Tool Reliability: A loose port can lead to intermittent connections, making it difficult to get reliable readings from your OBD2 scan tool.
By correctly locating and securely mounting your 1995 Miata’s OBD2 port, you ensure smooth inspections and reliable access for any necessary diagnostic work, keeping your classic roadster running smoothly for years to come.
