OneGauge is happy to partner with LRB Speed to provide a 7″ screen setup for NA and NB Miata MX-5’s.
This kit includes the following, plus any accessories added as optional purchases:
- OneGauge Hub, ABS plastic case, and power wiring
- 7″ LCD screen pre-loaded with all current OneGauge themes (see TheOneGauge.com/Themes)
- Bluetooth connection for use with Android devices (connects directly to Torque Pro or RealDash)
- LRB Speed cluster housing, pre-cut to fit the 7″ screen. This will easily replace your current cluster and install in the same location with the same mounting hardware.

This Miata kit supports use of the factory oil pressure (89-94 sensors only) and coolant temperature senders in NA and NB cars (wire splicing required), as well as the factory tachometer output. Inputs for voltage, fuel level, turn signals, and two indicator lights are standard with each kit. Purchase of a GPS speedometer is recommended. For Miata specific installation instructions, see the bottom of this page.
Sensor Input Options:
- Standard Sensors – use standard, automotive grade sensors installed directly on the engine or in the vehicle (much like typical aftermarket gauges)
- Each OneGauge includes free voltage, fuel level, turn signal, and tachometer inputs (tach adapter may be required, see tachometer instructions).
- Factory Miata coolant temp sensor may be used (please let us know if you have the NA or NB sensor)
- Factory oil pressure sensor will only function if it is not a “dummy switch” style sensor, as found in 1995 and up Miatas. This sensor will either need to be replaced with an NA sensor or with a sensor supplied by OneGauge.
- Additional indicator lights can be incorporated, please reach out if you need more than 4 (including turn signals).
- This is a good resource for wiring your cluster.
- Wireless OBD-II connection- for engines made between 1996 and 2008; due to slow data speed we recommend a GPS speedometer and direct connection to your tachometer for best results. To learn more about OBD-II setups, please visit the OBD-II info page.
- Wired OBD-II connection- for engines made in 2008 or later. To learn more about OBD-II setups, please visit the OBD-II info page.
- CAN-BUS connection- for aftermarket or standalone ECUs or EFI kits with CAN BUS output. Please see our Features list for current compatibility.

Miata Installation Instructions:
Removal of the factory cluster is simple and there are many videos and tutorials out there, including our own install series.
The factory wiring can be spliced and wires run directly to the following screw terminals of the OneGauge hub. Screw terminal labels and diagrams are available in the instructions on TheOneGauge.com/FAQs. Great wiring diagrams are available here.
NA Miata wiring:
|Connector 1: White||Old||New OneGauge Wire||
|Ignition Switch||Black/Blue||connect to alternator below||–|
|Alternator||White/Black||connect to Ignition above||–|
|Connector 2: Black|
Note that the alternator/ignition wiring is just a precaution and may not be necessary. The alternator seems to be self-excited on NA Miatas.
TEST EVERY WIRE before installing onto the OneGauge system. Coolant temp, parking brake, fuel sender, and oil pressure connections should all have NO voltage running through these wires when disconnected from the factory cluster. If any voltage is present, please reach out to us.
NB Miatas use basically the same wiring, except for the tachometer wire on Connector 1 is Black/White instead of Yellow/Blue.
