Fuselage wiring harness

Tonight I finished installing the right hand side harness. I drilled holes for the headset jacks, installed them, and then installed the 12v power socket and aux audio plug.

The headset jacks need to be isolated from the airframe, so I measured and enlarged one of the two holes to fit the spacer washer. Then I located and enlarged a new hole for the LEMO jack, and installed all of the jacks on the right hand side. I covered the ports with electrical tape to prevent debris from building up.

With that done, I moved to the 12v power port and headset jack. The 12v socket installed easily, and I had that installed quickly. The aux audio port was wired for a molex plug, but the small pins were very annoying to work with. I decided to use d-sub pins and sockets to connect the port, and that worked out much better. If the port ever needed to be replaced, the heatshrink can be carefully sliced open, and the pins separated.

The harness extending all the way aft and plugging into the tail cone harness. There’s a little bit of slack in this section, so once I have the other end hooked up to the panel, if the slack remains, I’ll secure with adel clamps.
The harness extends outboard to the wing root. Just before it passes outboard, the headset jacks branch off.
