AC heat Controller conversion???

hey.. can I convert my standard AC, heat controller to ..one of those cool looking Digital AC, heat controller from VR4??? Will i have to mess with the Radio or anything else before taking them out??..Instruction for this anyone??..

Extra question!!.. how do you spin tires while keeping the car in one place??..I know this sound stupid, but it's kindda cool to know how. haha

Hold your brakes, and the gas at the same time, apply more pressure on the gas until they spin.
As far as converting to the digital readout...I would think it possible, because some SLs have it, but I don't have the instructions for it...sorry
Anyone else?

instructions can be found on 3si. a chicagoland guy did the swap from a RT to his SL. There are a lot of small parts though.
