Without the two sensors will the HVAC work? Seems like you could adjust it to hot or cold but not set a specific temperature.
Also, what year is it from?
Thanks for the update. Just to clarify, is the first link the night vision Camera that will work properly with the 8.4? Or is it a cable adapter that will make the Jeep camera work with the Ram 8.4?
Based on the numbers of your stock and take offs I would guess you won’t need the spacers, but can’t be certain. I did need spacers and did not see a need to change LCA to fix castor. It drives fine.
