I started the integration of the wire harness into the aircraft by terminating the Push to Talk and Auto Pilot off wires to the control sticks. I also routed the audio headset wire bundle into the tunnel. As a diversion from wiring, and to confirm my wire routing would not interfere, I installed the heater scat tubing. What a pain to get to the front connections. The audio headset plugs will be installed in the center console.
