Finished avionics wiring harness: 6 hours


  • The avionics wiring harness (except for engine sensors) is complete! I will be installing it soon.
  • Finished GTN 650 data wiring.
  • For power wiring on GTN 650, which requires splicing a larger wire into two or three wires multiple times, I decided to use the solder splices. They worked great. Next time around I will use them more often - much easier than the soldering iron!
  • Connected GTN 650 configuration module and fan connector wiring
  • Assembled all GTN 650 backshells
  • Organized wire harness
  • Added power and ground wires to GMA 245R audio panel connector and GTX 23R transponder connector

A lot of shield drains on the main GTN 650 connector:

Solder splices work great!
