on mine the wires are:

blue
blue w/green stripe
white w/green stripe
yellow w/green stripe

the aux cable i have is has two wires for both left and right (red and white).. yellow wire and another wire (with no color) and white wire with another wire (no color on that one either)

any idea how to match these up? i have the adapter to plug into the back of my alpine deck.. i'd rather not guess and check with the many different combinations. has anyone tried this yet?
