O.k. maybe this thread isn't in the right place if not please move.

I bought a new aftermarket stereo in-dash dvd w/ nav. to it. and i have to hook a wire up to the parking brake detection switch? in order for it to operate. now i know that some people can bypass this which is what i want but i figured i atleast needed to start by finding this switch or if someone knows how to bypass it and where to find the wire to do so that would be great since that's what i want anyway. But the none of the stereo will work without something being hooked up to it i need to figure something out.

thanks
