Alldatadiy.com should have the wiring diagram.

Hi, your factory Sunfire wire colors are pasted below. The yellow wire should be accessory. This should connect to the stereo's red power wire. The orange "always hot" wire should connect to the stereo yellow wire--this is only used to keep your station presets in memory. Please let me know if you have more questions, and thanks for using FixYa.
