Ive been driving a 15' p85d loaner for a month and a half and I've realized the only thing my ap1 oct 14' p85+ is missing is the auto close charge port door. Does anyone know what would be involved with adding an auto close charge port door? Somehow my wife and I always find ourselves at the nearest stop sign from home running back and closing the charge port door. If I added the hardware, is there wiring already there and would my software know to use it?
