Prior to close-out on the vertical stabilizer I ran the wiring for the VOR antenna and beacon that sits on the rudder.
This requires drilling of additional holes in the center ribs and inserting nylon snap bushings to isolate the wires preventing chafing.
I used a pre terminated wire on the top of the vertical stabilizer to connect to the base of the VOR antenna. Once the skin is applied you will lose access to this area so using a factory assemble termination was worth it to avoid any problems down the road.
I also wrapped the beacon wired harness using a expandable nylon wrap and closed each end with heat shrink tubing to hold the wrap in place and eliminate fraying of the material.
Later I replaced the beacon wire harness with one purchased through Midwest Panel Builders that had all of the wired pre-terminated and included molex plugs.
This harness was also wrapped as shown below, though it is quite difficult to replace the wire after the skin is installed it is possible. I enlisted the help of my daughter to help as her hands were much smaller and could fit through the lower spar and feed the wired through the nylon bushings.
