The pinout isn't all correct for a Mazda MX5. I couldn't dim the radio by turning on headlights, so the auto dimming functionality was lost on the head unit I bought. For context, I was installing this in a NC2 with Bose. I called idatalink and told them after taking it out and looking at it again it was missing the illumination pin, and they told me that despite spending $200+ on the RR, this harness, and the Kenwood specific adapter harness, I would need to tap the illumination wire from the Kenwood harness and then tap it into the factory harness myself. Granted, if I hadn't needed to it would have made everything plug and play and mostly easy, but if I'm tapping one wire I might as well just build the whole thing. For some reason my Kenwood radio also lost the beep functionally when using this, but those functions work when using the harness I made with the Kenwood harness and a Metra one. All in all I I ended up taking the much less expensive route of making the harness and using an ASWC-1 for steering wheel controls for way cheaper.

Great product, I’ve used it in my 05 Mazda3 as well as my wife’s cx-5 and install was quick and easy

The harness is good, kept majority of functionality. It is required if you are getting it with the maestro universal replace radio. Got one on amazon but can do a review on this for information purposes
