Leaving aside the issue that an enquiry written in txtspk is less likely to get a sensible answer, putting a mic of any sort into a light aircraft cockpit is unlikely to give any useful output, particularly received audio from ATC.
Hopefully there is a spare tel. socket in the aircraft, and a simple tel plug to 3.5mm plug (or 2.5mm depending on the device you are feeding the info to) will have the desired audio feed. If there isn't a spare socket, the tel splitters are readily available to allow this. This works on Senecas, so I have no reason to suppose it won't work on anything else.
