I Removed my dash board and noticed that there is a plug leading to the dash and connects right into a hunk of plastic and does nothing. I am guessing it is a power line just incase the owner wants to add another 3 cigarette power port on the dash. Does anyone know where I can buy the plate / cigarette option? I searched ebay and google and got nothing. The port I am talking about is under the left airvent in the image.
