So looking change out my cheap Chinese tow mirrors on my 2014 Silverado to the am auto with power folding and puddle light I already did the rzy and diy boost auto door harness my question is did I need to just change out the mirror switch to have the the power fold work and I also thought about hooking the puddle light to the dome light circuit tapping off connector x7-1 or x8-2 so it turns on when the door opens
