I am installing an Icom radio and a Sigtronics intercom in my -7A, and have a question about connecting the two. The wiring diagram for the intercom shows 3 wires that connect to the radio: one to the radio headphone output, one to the "key input of the aircraft radio" and one to the "mic input of the aircraft radio". The headphone connection in clear, but I am confused about the two mic connections. The radio wiring diagram shows a yoke-mounted communication/intercom switch between the radio and the microphone jack to use the built-in intercom feature, but I do not need to use the switch, I believe. If anyone is familiar with the Icom radio and can offer advice, it would be much appreciated. Hope this is clear enough.
Thanks.
