Add-on for Passenger Side HVAC Blend door wiring with 4 speed Conversion Fan harness set or with 2014-18/2019+ Classic 1500 ATC Part 2 Harness. Custom Build (1-3 week ETA typ.).


NOTE: Single Zone ATC is an unofficial Ram HVAC mode and is dependent on 3rd party vehicle BCM programmers ( AlfaOBD, OBDgenie, etc.) to function correctly after programming changes made by the end user/owner. Correct operation cannot be guaranteed. Additional wiring to support factory mode, Dual Zone ATC, is available as an option and requires additional parts/dash removal/blend door install which is also dependent on the end user/owner. See the following RamForum thread for details: Adding dual zone atc to a tradesman.
