I tried this site: https://www.mazdaforum.com/forum/vindecoder.php

That did not give me any specifics on the features of the vehicle.

I was wondering if anyone has heard of this model. I have a 2007 Mazda 3 hatchback that is labelled as a luxury edition. It has everything a GT model has and more. I am trying to find wiring diagrams...

You talking to me? You don't like my idea of fixing the pulley with a bearing rather than replacing the whole thing.
Its not helpful to offer people other options? Isn't that what this forum is for?...

2007 Mazda 3 here with a noisy pulley. Pressed out the old bearing and pressed in a new one $5.00.

Head over to Princess Auto and grab a 6203 bearing. Then take off the pulley and press or bang out the bearing with a socket and install the new one.
$5 and your done for a few years till next time.
