Mine did not come with it, but everything was there. I bought the controls, cut a hole JUST big enough for it to fit. Then all that needed to be done was to attach the connecter that was already under the steering column cover and attach it to the mounting post that was already there. One of the best "upgrades" I've done.
Not sure if it's the same on the earlier models or not, but doesn't hurt to look before purchasing unneeded items.
