What Kind of Cable?

What kind of cable do you use when you want to connect the steering wheel controls to an aftermarket head unit?

I ask this question simply because i want to get a Panasonic head unit, and my Monte Carlo has steering wheel controls. I know the stereo comes with a remote, but I was wondering where i could find the cable to hook it up, and about how much it would be. If I find it for cheap enough i might as well do it simply to keep the ease of driving with those controls.

PAC makes boxes that do that .... there is no real "cable" for that. The wires for the steering wheel come out in the harness that plugs into the radio.

and you have to have a compatable headunit also what model headunit you have
