aux input 2001 tahoe

i have a 2001 chevy tahoe and i have the stock stereo in it. it is the one with the casseste tape lower in the dash. i would like to illiminate the tape deck and use the aux in as an aux in. can i get some wire info like what wires do i cross to trick the cd player into thinking theres a casete in it, and what are my inputs? are the high inputs or low inputs? wire coloros would be very help full. thanx
