@TinkeringFox thank you very much for all your efforts at figuring this out for everyone...
Thanks everyone who took time to make this thread as awesome as it is!
Just ordered the same one myself, I have a 2017 1500 with the 3 button configuration, and this was like finding the holy grail!
Now to figure out what to wire to all these locations... I have 1 and 2 figured out but 3/4 I'm not quite sure what to do with yet???
