Congrats. This was the entire reason I purchased AlfaOBD in the first place. Well, there were a couple others but ATC is one of the best mods. Set it and forget it...I have successfully completed the ATC in my truck. I have a 2014 Bighorn 2500 that was factory with single zone MTC. I did NOT need the harness for my install as the factory plug was there. All I needed was the temperature sensor.
