I haven't gotten around to it yet. After the I've been too busy try to make money.
It hooking up the CC will be really straightfoward you won't even need to cut any wires, just push the horn wire lead out of the harnesses and then slip it into the one with the CC. The question is how to best mount it. The CC "swith" itself has bracket that holds it into the steering wheel so its just a matter of fining a suitable location to mount it and then trimming the cover.
I just haven't had the time to take off the cover look at the steering column, but when I do I will document everything. I have gotten used no CC, but would like to have the use of it eventually.
Maybe I'll try this next weekend since everyone has been asking. The wheel only took 20 minutes to install, but I'll assume that this project will take a few hours. (at least the first time)
