How Does Redarc BCDC RED69FR Install

Question

Question:

I had my Redarc BCDC1212T installed on a trailer. Now installing toward rear of 2021 Ram 2500 Big Horn ear 7 way connector. I can not find directions for this. Wire to ignition, check. Get power from 7 way? Seems I would not need to tap into a different wire for power. Also do I need to run the brown wire to trailer battery. I diagram or video would be great.
