Avionics Wiring Harness: A Tutorial

[Eric Page]

In the posts that follow, I’ll show the fabrication and assembly of a short interconnect harness for the Dynon SkyView network. Most other avionics systems will use similar harnesses that can be fabricated in the same way. Hopefully this will help to demystify the wiring of a modern glass panel.

I’ll cover the topic in four parts:

• In Part 1, I’ll go through the tools required for the job, and I’ll provide links for examples that I’ve found to work well.
• In Part 2, I’ll list the parts and materials required to build a reliable harness, again with links.
• In Part 3, I'll show the wiring and connector pinout diagrams.
• Finally, in Part 4 I'll demonstrate the process to fabricate a harness from start to finish.

Just because all of this made sense to me when I wrote it, doesn’t mean it will make sense to anyone else, so feel free to ask for an English translation!
