What format is the OEM Backup Camera? CVBS or RGB?

[socalexpeditions]

Not sure if anyone will know this answer, but is the rear camera part no: 68274731AE CVBS or RGB camera?

This is for a 2018 Ram 2500 Tradesman that came with the RA3 radio.

I ask this because I know Android 11 Headunits such as the one I purchased below will work in retaining the OEM backup camera if it is CVBS. If it is RGB, it will not work.
