So I figured out why my backup camera was not coming on automatically when I put the vehicle in reverse. There was an extra wire, it was pink on my head unit connector, that I needed to connect to the reverse wire next to the steering wheel. The reverse wire was light green on my 2008 Toyota 4Runner. This wire is different from the reverse light wire that I connected the backup camera to.
The installation instructions for the head unit and the backup camera left this step off. Luckily I was able to do research and figure this out.
Backup camera is now working as it should!
