CD Changer Aux Input

[InfiniteGSX]

I've read about other manufacture's having something like this done. GTO's you can tap into two different area's including the phone button on the Blaupunt stereo. The CD/Tape/AM/FM stereo in the older Chrysler Dakota's and Jeeps are more of a bi***, gotta cut the audio going into the stock pre amp and split it into two with a special switch/relay... It blows!

However this car has a CD Changer. I have both stereo's, The Tape/AM/FM/Aux and the one that doesn't have the Tape player nor the aux input. But both have a CD Changer output and this car has the stock changer, however I don't have the Cartridge and.... Seriously.... CD's?

I know how the CD Changer works essentially, it has left and right positive and one or two negatives for the audio from the cd changer to the stereo's input, power and some other stuff.

But Which wires are what? How could I get the stereo to believe there is a CD.... I know the CD Changer control has the ability to control the ipod using a lil adaptor but IDK what adaptor works and I don't need to worry about it.

I just wanna wire in something like this:

Any thoughts? I'm sure someone had to have done this.
