2003 Radio Harness Diagram

I've been searching the forums and I can't find this anywhere. I just bought an aftermarket radio and harness to fit my truck, but something is not right. I'm concerned that the harness I picked up on ebay isn't lined up properly, even though it fits the plug perfectly. Is it possible to get a description of each wire in the factory harness? I have an '03 F250 with the in-dash 6 CD changer. A diagram would be great. I'm hoping its just a wiring problem and not a probelm with the head unit. Thanks!!!

The wiring diagram in the Chilton's manual is correct. I had to re-wire my factory radio when I bought my truck, and even though the year listed isn't correct (I think the year listed on the diagram is 2001). I can take a look at it when I get home (at work right now) and post my findings.
