How to add cargo camera and connect to 8.4

[ardvark666]

Hi all, I have been looking at these forums for a while. I have a 2019 2500 with the 8.4 and just a backup camera. I bought a camera for the cargo from brandmotion fltw-7626. I also got the cable to add it to the backup camera that allows me to toggle the camera. Is there a way to add it to the 8.4 as just the cargo camera? I ordered an obdlink. Im trying to figure out how to connect directly to the radio though? Anyone know the easiest way?
