I know this is a old thread, but I felt it is better to respond here than making a separate thread about essentially the same thing.
I just bought a 2014 Ram 1500 and is almost ready to do the RA1 to RA2 swap. I'm also thinking of getting the mirror and harness setup--or the Amazon mic route if that would be easier. The only thing that is stopping me is the location of the harness to plug the mic/mirror. Is it on the end of the passenger side dash near the far right AC vent? if so, how do I take that part of the dash off to reach it? I've searched for this on the internet and didn't find an answer.
