I saw a thread regarding this some time ago but can't find it again by searching. I decided to upgrade my leather steering wheel on my 2009 599GTB to a carbon LED wheel after seeing one member posting about it to ask if it was plug & play . I do remember the advice was that it was, but you had to use the menus on the dash display to turn on the LED display function on the wheel . I have bought a 599 carbon LED wheel but when fitting it have found that it has 2 extra wires in it that the old wheel didn't have, plus nowhere to plug them in. Any ideas ?
