How to add an extra AUX audio input?

Hi, I have a honda element EX and I am trying to add 1 or even 2 AUX audio inputs.

Does Anybody know how to splice the aux? and have 2 conenctions extra?

Basically I am trying to do a full behind the dash install of Ipod and Sirius. That's why I have a thread for power and one for audio aux.


Thanks so much!
