Riveted a standoff to the aft mid-cabin cross member to support the pitot and static lines that run to the Garmin G5. Routed the lines, cut them to length and connected them to the G5
Soldered two 20 gauge wires to the backup push to talk switch, twisted the wires together to make a twisted pair and installed the switch in the LH sub-panel.
Installed spiral wrap over the headset wires under the LH cockpit rail above the throttle quadrant.
Began terminating the pilot headset wires and installing them in the connectors for the GMA-245. Connected the wires for both pilot push to talk switches (primary and backup) to the pilots mic wires.
Realized towards the end of the work session that I had the J1 and J2 connectors reversed so that the wires from J1 are in J2 and vice versa. Fortunately the wires are long enough that I'll be able to switch them.
