Hello Novus, when I say "plugged it in" I mean the mirror has a female end built into the frame, when you bolt the mirror in place, its portion of the plug is in place. The wiring harness end is right behind the door tweeter, which simply snaps off. If your current mirrors are good, the plastic painted portion unclips ( carefully) and will snap into the new one. I still did not replace the left one as I am waiting for it to show up from the dealer. I expect no issues, but you never know. I will report back when I install the left.
