Can U HELP?! '95 E320-Wiring diag: 10 pin Connector??
 

I have a 1995 E320 Sedan. I'd like to add a (stereo 1/8" phone plug) connector somwhere in the cabin so I can connect an iPod, or any other AUX type device for input to the stereo system. I'm guessing one easy way would be to tap into the 10 pin connector in the trunk.

Can anyone give me the info I would need to identify the correct wires to tap into?

Is there an easier way to do this that I should consider? (If it means taking apart the dash to remove the radio, I think I'll stick with my current plan.)

Thanks for looking. Thanks even more if you can respond with answers! :)
