The main wiring task left was to terminate all the wires and cables going through the overhead console. We started by securing all the coax cable (8 total - 4 for the TAS, 3 GPS, and 1 for XM), then grounding all the ground planes together and connecting that to the firewall:

I then terminated the overhead light wires and O2 distributor wires:

While working on that, I realized the inserts I had already cut needed changes in order for the O2 DB9 connector to not hit the nutplates, so I spaced them further apart, moved the GoPro mount to the (lateral) center of the forward insert, and moved the AMPS hole pattern to the aft insert (this is meant for a RAM mount to secure a tablet or similar for passenger entertainment). I'll have that fabricated in the next few weeks so I can finish putting the overhead together.

With that, knowing the position/length the coax cables needed to run through, I could also terminate them on the panel side:

For the GTN's GPS connection, the cable was close to the panel rib, but thankfully still far enough to be safe, once the panel was mounted in place:

The parts of wiring left are the switch pod, heat servos, flaps, the O2 regulator, and most of the FWF wiring.
