I too am a bit disappointed when my new 2019 Silverado RST with every available option but a sunroof didn't have an auto dimming mirror. My 2013 Silverado LT had one and I honestly never even thought about it having one until now I don't have one. Much appreciated for all of the information here...I just ordered a mirror and hope to do the install in the next couple of weeks.
Just to confirm...do I need any kind of wiring harness to install this or is it plug and play once I find the tucked away connector?

BTW...My wife noticed too last night that she doesn't have a lighted mirror on the passenger side sun visor...nor is there one on the driver's side. MSRP $55,000 and can't have the couple of things my 2013 LT had. ?
