Oh man Aaaaaaaayush!! This is the post I've been looking for to give me hope that I can add power folding to my 2020 Trail Boss LT. If you have a minute, I have a couple questions about your install:
1) Mirrors fold in and out only from key fob activation, you're not using the panel button?
2) Does the heating and all other controls still work without issue?
3) Were you able to get the perimeter lighting working or did you already have the safety package that enabled it? If you didn't have the package previously, did you do anything special to get that lighting to work?
4) Does the blind spot indicator need anything additional to work, or is that all built into the mirror?
I never even thought about using a separate power fold controller. I wonder if the aux button panel I've seen some people install would be able to activate the fold/unfold function instead of the door panel one. Thank you for your post, as I won't have to figure out how to do the memory seats now (hopefully).
