Re-wiring cruise control buttons
Since I never use cruise control, I want to re-wire my cruise control buttons in the stock steering wheel to control volume on my stereo.
I skimmed through the FSM, but didn't find any details on the CC buttons.
My question is: What do I need to remove from the steering wheel to get to the cruise control button wires? (Air bag, the entire wheel?)

If I remember right the cruise control button assembly attaches to the wheel with two screws. Just feel around behind it, and you'll find the holes. Once you have those out, pull of the assembly and the wires should be in sight.

911GT2, thanks for your response.
Well, it turns out those screws are actually hidden by the plastic piece on the back of the steering wheel. But, luckily all I had to do was remove the airbag (three nuts on back of steering wheel) to get to the cruise control wires.
Of course, after removing the air bag I saw what color wires were coming out of the cruise control buttons and just traced those to a connector under the dash. I can just tap into that pretty easily.
The problem now is that it turns out that there are only two wires coming out of the cruise control buttons. All the buttons do is change the resistance between those wires.
That means it's not going to be as easy as I thought to control other hardware with those buttons...I wish I paid more attention in my electrical engineering classes...
