I need to route the GPS and NAV ARINC outputs of the GTN650 to both my GRT EFIS and also my Garmin GAD29. The GPS ARINC was already daisy-chained from the GRT ARINC module to the old TruTrak autopilot (long been removed, but the wire was still there). I needed to add on a "Y" to the ARINC NAV wire. I was really regretting this, its very far back under the panel and just a pain to get to. It took a solid 2-3 hours with frequent breaks to get this wired up.


I really don't like the cheap plastic D-Sub backshells. I ordered these Amphenol FCI backshells that were all metal. They are VERY NICE, and easier to put together in tight spots. I am a big fan. Part #
