Hello! I have a 2019 Big Horn 2500 6.4 and I've swapped my radio to 8.4 and the bezel that came with the radio has automatic temperature control. I know that I will need to add a cabin temperature sensor 55111178AC to the knee bolster area, but unfortunately, at least from what I can see, there's no wiring present for it. Any idea what would be needed/how I can add this to my truck?

I offer that add-on harness for those that do the swap. PM me if you want one. You also need the correct solar sensor in the center of the dash.
 
@Jimmy07 - Details on this upgrade? I'm wanting to do the same on my '20 2500 Power Wagon w MTC.

Digging this thread up. Hoping to add single zone atc. So 55111178AC is the temp sensor. Does anyone have the part number handy for the solar dash sensor?
 
For anyone looking, Jimmy confirmed with me the sun sensor is 68230114AB. I will be attempting to add the atc without changing out my bezel to the "auto" button. According to OBD Genie's site, they say their programmer can add atc to those with AND without the auto button bezel so it should work out. I'll be using AlfaOBD for my programming changes though.
