Got the pitot line installed which will connect to the pitot tube. It measures how much pressure is being pushed in the front of the tube and compares it to the static pressure in free air on the side of the aircraft. The calibrated difference outputs to the airspeed indicator while the static pressure outputs to the altimeter and vertical speed indicator. If you didn't recognize it immediately, it's the curved tube with the big blue nut at the bottom of the picture below.
You can also see the bellcrank with the two pushrods attached. An elegantly simple system. The larger pushrod connects to the bottom of the stick in the cockpit. The smaller one which is going up in this picture (aft when the wing is level and not held in a jig) attaches to the aileron.
Here's a youtube video with a lesson on pitot static systems.
