That cable is used in a bunch of different models, so it shouldn't be discontinued any time soon. drill a 1/4" hole in the panel under your center console and pop that through, it is a panel mount aux connector so you mount it anywhere.
For the wiring, just pop the pins out of that black connector and then pop them in to the (same) black connector in the same spots that is already behind your radio.
This version actually looks a lot cleaner after the install than the factory version in the 07s and 08s.
