Hey everyone,
I just bought a 2013 mazda 3i. SV used obviously lol. I'm trying to install a new pioneer headunit that I got today. I have never installed a stereo In a Mazda so I'm just trying to be cautious about it. Does anyone have a stereo wiring diagram?

I would very much appreciate your help lol. Thank you

Harness adapters are readily available. They plug into the factory harness connectors and give you clearly marked wires to splice into the wires from the new stereo. Crutchfield is a good resource for recommending the adapter you'll need, and will also show if you need any special bits to make sure the car's features still work, such as steering wheel controls.

If I can't get some type of credible diagram I will end up buying a harness adapter. I really don't have money at the moment I literally just spent what I had on this pioneer lol. But I do appreciate you giving me a solution to my issue. Thank you

The adapters are like 10 or 20 bucks. I have always considered it bad form to hack off the factory connectors to save $20. But it's your car.

That's understandable 100% I have cut the sterwo harness and spliced it all before and it's usually not the prettiest ending. But I have not yet found a harness that will let me keep all my features except for Crutchfield and it was like 100$. But what I think ima do is order the steering module to keep steerwheel switches and a harness with the other features. TNS , OBD. And then solder it all together. I haven't found a harness with the Adapters I need yet though. To be honest I got the wiring diagram and triple checked it was right and it is but making the harness with out the module is impossible and to take off the features is not something I really wanna do
