Finished Tailcone Wiring

With the ELT shelf riveted in, I wanted to finish up all of the tailcone wiring.  One of the final items on the list is the cabin light wiring.  I ran three 22awg wires from the front up through the top of the baggage bulkhead.  This will be inside the cabin frame support and will connect to a small LED spotlight that will have both white and green lights in it (hence the two red wires and one black ground wire).

I then secured all of the wires from the left conduit with an adel clamp on the ELT shelf rib and some zip ties.

I also ran an additional RG-400 cable through the right conduit for the Garmin GTN-635 GPS antenna.  I had originally planned to mount both GPS antennas (the Garmin and the Dynon) under the cowling, but the Garmin install manual stipulates that GPS antennas not be installed closer than 9″ from each other and require a 7.5″ minimum radius ground plane under the antenna.  Though under the cowling would likely work just fine most of the time (and I’m still going to mount the Dynon antenna there), I want the highest possible antenna performance for my primary IFR navigator.

I finished all of the wiring runs up to the area behind the subpanel, though the cabin light ground is the only wire I could actually hook up to anything.
