I just did the hardwire install, piece of cake. Thanks for the suggestion on removing the A-pillar, that helped a lot and made it cleaner in my mind. To make re-installation of the A-pillar easier, I also pulled up the rubber moulding around the door frame. All you do it just pull on it until it slips off the frame, very easy. Plus it allowed me to slip the wire from the V1 completely behind the glove box for a nice clean look.
