I got back into the process of wiring the airplane today. I began by installing the Comant CI-105 transponder antenna on the belly. I mounted it about 8 inches aft of where the autopilot pitch servo will be located. I also began running the RG-400 coax from this location forward. I'll crimp on the connector soon, but I need to buy a BNC angle connector first.

Next, I removed the old 4-conductor ELT phone cable and installed the new, thicker 6-conductor cable. [Superseded.]

As is always the case when I squirm into the aft fuselage, things take a lot longer than I think they will. On several occasions, I had to extricate myself to get a different size wrench or a different tool I needed. It's not easy to get in and out of there, and I will be very happy to someday remove the work-floorboards for the last time. While back there, I re-ran some of the wiring in the aft fuselage, added an Adel clamp or two, and prepped the magnetometer shelf for installation.

The final project today was to remove the strobe power pack, since I've decided that LED technology is now the wave of the future -- and dragging 5 pounds of power pack around is simply a waste. It pained me to remove the nice mounting plate I'd created (leaving the attach angles in the airplane to be admired for years to come...) but such is the price of progress. Maybe someone else can use the unit.
