2017 stereo wire harness?

So i just spent the entire morning searching Google but i can not find a wire diagram that shows me everything i need at the back of my stereo that looks just like mine.... im looking for right and left REAR speakers, remote, 12v power, and ground.... think i figured out what to use for ground and remote but definitely need L and R rear speakers + and -... best 12v and ground would be cool tooo... check the pictures and see mine is different from all the info i can see.
