2018 Mazda 3, Speaker, Remote, Reverse Wiring

Hi first post, long time lurker, I am looking for the wiring colors for my 2018 mazda 3 non bose, I need speaker wire colors, remote, and reverse signal ( I read that the backup signal needs to be tapped at the BCM, but if there is a way to tap it in the cabin id be happy) thanks lots

What are you doing?

powering my door speakers for a short run from passenger kick, getting a remote from somewhere, and getting a reverse signal for my backup camera
