Any luck with this? I’m in the same boat. I messaged with this guy on eBay and this is what he said:
“It includes all required equipment, wiring, and security code for the module. The trucks BCM will require programming changes for it to recognize the equipment change, and digital vs. manual temperature control. The ram dealer or really any auto repair shop with bidirectional scan tool can do this too.”
Unfortunately someone beat me on the auction since he replied after it ended. But let me know if you have any other info
