2018 Dodge Ram Upgrading from 5.0" Uconnect to 8.4"

[Jessman22]

i had recently picked up the 8.4" screen with the plastics you see in the picture was just wondering what else I would need to complete the set up from the videos I've been watching looks like I need a wire harness and a heater control module but not sure,, The 2nd picture seems like that's the only plug I would be missing for the heater control

I don't see if you have been answered.. but, yes. If you had 5.0" factory going to 8.4". you will need the conversion harness and HVAC kit. Contact @Mpgrimm2. he'll get you squared away.
