You'd have to buy an adapter that hooks up to the controls, then is wired back up to by your domelight, then theres a little infrared light thing (like on a remote control) that mounts up there. So your steering wheel controls would be like a remote control.
The stereo I'm getting put in tomorrow has an input in the back for steering wheel controls. (I think most Eclipse ones have that)
