Not sure where Mill Creek is either...
Not a problem and thanks for your efforts to help me. I didn't need to do anything re: the female end of the factory harness, which is where I got confused. The "adapter" harness from Scosche was easy once I understood that and it turned out perfectly.
I am amazed at the quality of the speakers that came stock in this car. For my ears, they are good across the spectrum powered by the Kenwood KDC-HD552U... no sub that I can see... but deep bass response.
I especially like being able to control and play music from my iPod (which is also pretty amazing through this head)...
thanks, Ford, for keeping up the quality without participating in the bailout fiasco!
