colors of wires and plan for the AUX input ?

[tforand]

Hi,

I have a 2002 K12 with CD player and "AUX" option.
I simply want to plug different things like iPod or GPS on the "AUX" input but I don't know where it is on the radio plugs !!! (3 plate and 1 rounded).
Can you help me by telling me what plugs is the "AUX" input and where exactly and what are the exact color of wires for + left, + right and common left and right - ?
If you have a plan or a picture I would appreciate.
If it's not loud enough, I would use a ampli.

I don't whant to use a Dension connection or FM transmitter.

Thank you and ride safe.

Sorry for my poor english.

Here's the basics, the two 10 pin connections on the bottom seem to be the same, so which ever one the CD Line in is plugged into, you can use the other.
