Installed the TD91-79-CFZ-V6-029. This the module and harness for my application from mazdaparts.
The install is not difficult but my warning is to be careful of stamped steel under the dash. It is very sharp and it cut my hands up.
There are changes over the years so I want to mention that this install for my application will allow the Sirius radio, front aux input and Bluetooth to function normally. The harness appears to include the switchbox (IIRC it looked the same as the separate switch I had installed on my '3'.)
