I am replacing the Shaker 500 in my 05 GT Vert with a 2008 model head unit.

One option is to use the stock parts: Can anyone provide the part number or part numbers for the auxillary jack and wiring harnesses to add this feature to my 05 GT?

On the cheap side, I can get a jack from Radio Shack and run simple wiring under the console, but connecting the wires to the radio may require a proprietary plug. Then again, if someone knows where the wires need to be connected to an existing plug module, that information would be greatly appreciated.
