I was reading the install manual and got confused about the serial connection. I am going to be making up my own harness. It appears that the serial connection, pins 9,10,and 22, are used both to connect to a PC to update firmware and to connect to the GPS to obtain airspeed data.
Pin 22 is the EFIS Rx pin on the D6. Do you parallel that wire into both a connector that will serve as the PC connector and also into the GPS connector?
