Hi,
Not sure this is as straight forward as people are saying, for it to work by just fitting a stalk control and a bit of coding it will depend on the exact spec of your vehicle, there was another member a few years ago tried to do this and was unable to. I,m sure it depends on the type of traction control is on your vehicle, as the cruise control system interfaces with it.
There is a thread on here about his attempts and I don,t believe he ever managed to get it going. Shude another member on here was successfull so it might be worth sending him a PM regarding it.
