what havent i done!!!, im turning the inside of my series 3 into something that resembles the starship enterprise! ive made a control panel which has 3 cigarette lighter sockets, with seperate on/off controler for each, plus a switch that turns on and off the control panel, i wired in a cab light with another on/off switch, i fitted a cd player and 2 6x9's (for when i break down and am waitin for the aa man!) which iv put in a homemade cubby box in the middle seat position, and also managed to make my lights not work! not bad for a weekends work, now about to make a snorkel...
