What's posted is a 2006. 2004 and 2005 have two pins on the sub end that use power circuit 828 (pins 5 and 6, 2006 only uses pin5) and two pins that use ground circuit 1204 (pins 2 and 3, 06 only uses 2). Also, the "shield" wire, circuit 57 that comes off the HU, makes no connection to the sub in 06, but does in 04 and 05.

One other note, I originally purchased a Metra harness to connect an aftermarket sub, but never got it to work. metra doesn't give pinouts, only wire colors. After buying the Ford connectors and using the shop manual, I discovered metra had their connectors 180 degrees out, hopefully I only damaged my old Sony amp and not my audiophile HU.
