Hello;
I purchased a prewired Garmin SL40 tray that has the following (5) wire desiginations that I think are intended to interface with the intercom: 1. mike key, mike audio L., mike audio Hi, phone audio L., phone audio Hi.
The wiring harness purchased from Van's for the FlightCom 403mc has has the following (3) wire desiginations for the interface with the com: mike key, mike audio and phone audio.
The question is: Which Garmin mike and phone audio wires should connect to the intercom mike and phone audio and to what should the additional wires be connected?
