All good things have a price. If you order a HU from Crutchfield, you can get 50% of of that harness price. But I didn't and spent the cashola. To me spending $330 to NOT have any cut wires, retain steering wheel controls and keep my Sync was worth it. But you have to decide for yourself....
The Axxess AFSI-01 I originally purchased may work if you have the factory base radio (non-amplified, non-sub). Save $100 if it works...

If you get the Axxess one though and you get the PAC-SWI - you most likely need to splice in and solder a resistor for the SWI to work. The good thing about my harness is that the PAC-SWI plugs directly in - no splicing, no running of power/ground and no resistor. Just plug and go.
Also get the updated PAC-SWI:

Cheaper at Sonic Electronics:
