Oem rear camera in mirror to android auto

[FirstDiesel]

I have a 2014 Trademan with factory rear camera that displays in the mirror. I have installed an Android auto unit and would like for the camera to display there instead. The unit came with an aftermarket camera so the plug is there for the camera. How can I connect my camera to my android auto?

You need the correct adapter cable for converting the old radio cables to the new one, and then an additional cable you can get from @Mpgrimm2 .
