I located many of the female "spade" type connectors in the airframe and added a small piece of heat shrink to each one to insulate it from any contact with a potential ground. I actually extended the heat shrink just a little beyond the tip of the connector for extra insurance. It does not interfere with the mating connector. These type of connectors are used in the airframe for attachment to LED indicators, certain instruments, and 12V aux power outlets.
I also have a bunch of these connectors that attach to the three fuse blocks. When plugged in to the buss they are not in danger of creating a short but if left "dangling" they could be a problem. I am considering using heat shrink on them also.
I also added a short piece of nylon conduit to protect the various wires that lay along the bottom skin of the aircraft under the pilot's seat. This will keep wires from chafing on any sharp edges.
I installed the DB9 shell on the autopilot servo lead. I may have to adjust this harness later to ensure it doesn't contact the aileron push/pull tube.
