3500 8.4 to 12.1 Upgrade

[Canadian3500bighorn]

Hi Everyone! I’ve read through all of the upgrade threads and have ended up confused on which part numbers I need for my specific scenario. I have 2022 Ram 3500 BigHorn 8.4 non nav. Looking to upgrade to 12.1. Would be super appreciative if someone can throw me necessary part numbers for this model. One more question I have manual heat/cool controls. Does this upgrade also change me to auto or are further parts needed. Sorry I know this has all probably been asked before, appreciate it!!
