Miata Audio Pinouts
News! - The Sylfex AuxMod is here - now you can have an auxiliary input for double-DIN/FMS Mazda head units!
Introduction to Mazda Audio Systems
This FAQ covers Miata audio systems from 1990 through the current models. Other Mazda systems will be added as information becomes available.
Mazda has a long relationship with Matsushita/Panasonic, so Miata audio systems from 1990 through 2000 are based on Panasonic designs. Descriptions of pinouts for these systems are found in the first part of this FAQ. In the early '00s, Ford and Mazda partnered with Sanyo to design a new modular audio system. More information on this system is in the second part of this FAQ.

Note for 1996.5 cars: Mazda changed head units partway through the 1996 model year. Specifically, cars made prior to December 1, 1995 had the older units and cars made after that date had the new model.
How can I add an Auxiliary Input (Aux-In) to my head unit?
Every Mazda head unit can be made to accept audio from an auxiliary input. This is useful for connecting MP3 platers, sattelite radio, etc... Here's how:
All head units
All head units can use an FM modulator. This is a special device that sits between the antenna and the head unit and "converts" one frequency into an aux input. The pro is that this is known to work everywhere. The con is that it doesn't sound as good and can be just as expensive as the other methods listed here. Note that a real hardwired FM modulator is NOT the same as the dinky little handheld FM transmitter that most stores sell for $19!
1990-1996* base (non-MSSS) head units
The only way is to use an FM modulator.
1996*-2000 base and 1999-2001 Bose
2001-2005 base and 2002-2005 Bose
There is a project to build a special aux input module (AuxMod) for the double-DIN Mazda head units. I have one of these in my car and it works great! Entirely integrated and invisible.
Almost all Mazda audio systems from 1990 through 2000 use the same main and auxiliary harness connectors. Some also have additional connectors for special purposes, like external amplifiers or CD changers.
- CN702 (Auxiliary 8-Pin Harness)
- Round connector (13-Pin DIN)
- CN200 (CD/Tape Connector)
- MSSS Amplifier Connector
FMS Double-DIN systems (2001-2005)
All Mazda audio systems from the 2001 non-Bose and 2002 Bose use the same main and auxiliary harness connectors. There are two connectors on the back of the double-DIN unit, J-01 (main harness) and J-02 (auxiliary harness). Only the main harness (the larger one on the left, looking at the back of the unit) is used. Here is the connector pinout. This is the socket on the head unit.
See also the general Mazda pinout for advanced/extra functions.
The second pair of speakers (pins S, U, V, and X) do not function on the 4H60 (Bose) unit. This is probably a software, not hardware deficiency. In other words, there is probably some way to activate the fader function missing on the Bose head unit to enable these speakers, but it is currently unknown.
- J-01 (Main Harness)
- J-02 (Auxiliary Harness)
- Bose Amplifier (2002-2005)
- FMS CD/Tape Connector
