This afternoon I did a quick retrofit of the E9X accessory tray to get rid of the ashtray/lighter. Second vehicle I've done this on, and I moved the lighting to the front rather than the sides as the wiring was just a touch different on this car and they wouldn't reach. Quick, cheap, easy... great upgrade!
