Great product works flawless

The product came as described. I bought the button to add power folding mirrors on my 2015 Denali which had the old style tow mirrors. It works great and the install video was great but it was a lot of work in those tight spaces. Overall very happy that it works and all my functions work.

Easy plug and play harness

Watched the video before and during install, and it made it super easy. I am super picky about how I am about stuff like that making it nice and neat, so I’d say install took about 6 hours give or take with distractions.
