Compared the diagrams that I made last night as to each of the connectors on the audio panel, to the pins actually installed.
I discovered that I had some pins installed that were not on my diagram, and some pins missing. The missing pins are those that I installed today.
Determined that the pin in hole 25 of connector J1 was not connected to anything. I think I installed that pin in error in the past. I tried to remove it. I could not. That is probably why it is still there from the earlier error.
Determined that the broken pin was the com1 audio wire, which connects to pin 9. I had to carefully pick out the shoe goo to get to the hole. I extracted the pin in that hole which had broken off from the wire, attached a new pin to the wire and reinstalled it.
While doing the above, I noticed that the marker beacon antenna wire had broken at the pin, pin 1. The ground for the marker beacon antenna, pin2 had also broken. I removed them both.
