Multi-display clusters combine digital and analog elements. They may feature:
- LCD screens embedded in the traditional cluster space
- User-configurable data channels
- Integration with aftermarket sensors
5. LED or Indicator Light Customization
Upgrading the cluster’s lighting provides:
- Improved visibility (especially at night)
- The opportunity to match the interior’s color scheme
- Longer lifespan compared to original bulbs
Step-by-Step: Upgrading or Replacing Your NC Miata Cluster
Upgrading your NC Miata cluster may seem daunting, but many enthusiasts complete the process themselves with a bit of patience and the right tools.
1. Preparation
Before diving in, gather the following:
- A new cluster (factory, custom, or racing style)
- Screwdrivers (Phillips and flat-head)
- Trim removal tools (plastic preferred, to avoid scratches)
- Electrical tape (if making wiring changes)
- Optional: soldering tools, if advanced modifications are needed
2. Disconnect the Battery
Safety first! Always disconnect your car’s negative battery terminal. This prevents electrical shorts or accidental airbag deployment while working inside the instrument panel.
3. Remove the Trim and Existing Cluster
Follow this basic process:
- Remove any trim panels surrounding the cluster, gently prying them off.
- Locate and unscrew the fasteners holding the cluster in place.
- Carefully slide the cluster out, disconnecting the wiring harnesses at the back.
4. Install Custom Gauges or Faces (If Applicable)
If you’re installing new gauge faces:
- Disassemble the cluster by unscrewing the rear cover.
- Remove the needles gently—consider marking their original positions for accurate reinstallation.
- Place the new faces over the old ones, as per manufacturer instructions.
- Reinstall gauge needles carefully to avoid misalignment.
5. Wiring for Digital or LCD Upgrades
Digital clusters or LCD modules may require:
- Connecting new sensors (oil pressure, temperature, etc.)
- Interfacing with the original harness or splicing wires
- Configuring the display via software settings
Follow the manufacturer’s instructions precisely. Test connections before final assembly.
6. Reinstallation
Reverse the removal steps:
- Plug in all connectors.
- Slide the cluster back into place.
- Reattach trim panels and fasteners.
- Reconnect the battery.
7. Final Testing
Start the car and verify all gauges and warning lights function correctly. Ensure needles point accurately and the digital screens display proper data.
