as long as you have a tiptronic wheel with the buttons already its almost plug and play. because the buttons are linked together ie you can shift up or down from both sides of the wheel, you have 5 conections up/down up/down and power with the paddles ther is only 3 up/down power.
think i am making this sound more complicated than it is.
the paddles are then just wired to the right colour on the origanal harness.
up/down power(black)
up (green)
down(blue)
i will get some more pictures up its makes more sense when you can see it takes about an hour to do.
anyone in calgary canada wants help let me know.
this is the same as my wheel but in alcantatra
