I picked up my avionics stack from Aerial Avionics today. They’re a local company, but they were willing to match a price quote from I got from Stark Avionics. I got a PS Engineering PMA 8000BT audio panel and a Garmin GTN 635 GPS/COM.
They built the wiring harness as well. I went through the whole thing so that I could fully understand all of the interconnects. Other than installing an unnecessary marker beacon antenna cable (which I removed), everything looks perfect. Despite what looks like a rats nest, these are nicely organized and grouped together according to where they need to be routed in the airplane. The only mistake I made was forgetting to request that they use red wires for power and black for ground like I’ve done with all of the other avionics in the plane.
