I like to add two USB charging ports to the front and two in the middle row. In the front, I have no need for cigaret port so I guess I can replace that with a cigarette style USB charing ports. I don't care about the ash tray in the middle row and like to replace that with UBS charging ports. Are there any step by step process/video tutorials and/or kit on how to do this? What are my options? Many thanks in advance.
