With the servo situation all resolved and the harnesses run, I could actually install the pitch servo.

I staged everything I would need, tools, mounting hardware, lights etc and climbed in back and connected up the servo and tied off the wiring. It took awhile and some minor contortions but it went in very nice. I was also able to command it to move via the AP head and it worked like a charm.

The Yaw servo connector is at the bottom center of the last two pictures. It is not connected to anything.
