I finished running the LEMO (headset) plug for the Co-Pilot and the Pilot tonight. To finish the co-pilot wiring, I had to drill a second hole under the right rear armrest as the current access hole was too packed with wires. I then pinned the CPC after threading the harness through the new hole/snap bushing, installed the plug receptacle in the GIB's vertical bulkhead, and tidied up the wires to place the right-side GIB panel in place.
Wrapped up the CPC with self-splicing tape
Also applied tape for chafe protection at the bottom
