Installed the Metra 99-5823CH
I broke down and went with the Metra 99-5823. You can find other threads about pulling the panels off.
Ford Wiring Trickery: After spending hours chasing factory wires with a multimeter and wearing Google out, you won't find a 12v assessory wire. You will find several 2.5v wires. They must be combining the voltage somewhere in their integration thingys or pulling off some other overly-engineered stunt. Shame on you Ford.
You can either butcher the factor harnesses, run wires from scratch, or by the expensive harness. I broke down with the harness.
Some notes: The good thing about the dash is there's plenty of room and the panel are easy. The side panels in the back are a pain. Surprisingly, pulling the back seat out was the easiest thing of all. On a side note, I went ahead and put baffles on the back speakers hopefully to minimize the subs in the trunk from pumping them.
I'll add some finished product pics later of the dash kit.
