I am installing a TK-7180H Radio in an airplane for use in doing fire patrols. I need to interface the radio with the aircraft audio panel. To do this, I need to know the pinout of the accessory connector. I believe the following pins are used. Pin 1 is speaker out, Pin 18 is power ground, Pin 14 is 12 volt Switched Voltage out, Pin 13 is PTT, Pin 6 is Mic Audio Hi and Pin 25 is Mic Ground. Can you confirm these pins are correct for the functions?
Thanks for your help.
