Some of this prep work was actually started on the 3rd; I had to uninstall the battery and move the mount (easier than removing it) to the side so I could place some boards to lay on. To get in the area around the A/C valences (2nd Photo) and the rudder cable guide, I used moving blankets. Even so, it was a painful contortionist's act to work back there and a simple job took a long time. I routed the rudder trim cable and the tail light wire down the lower J-stringer on the left side, while the strobe cable and elevator trim cable went down the upper stringer. You can see in the first photo that I used caterpillar grommet freely to protect the cabling when transitioning into or out of the stringer. At the aft end, the cables were secured outside the snap bushings with zip ties to prevent them from pullling back into the fuselage. I also routed the supplied ELT antenna cable, using conduit and leaving the major service loop at the ELT end. That's it for the inside of the tail cone; I can make the aft connections from the outside. Now I can install the A/C package tray and oxygen bottle, which will complete installations behind the baggage bulkhead.
