(must be Aera 550 questions week)
Question is how to wire a Aera 550 audio fees with bare wire to a GMA 340 to get the audio alerts? Three wires off the 550 are simple (left-right-return), but lots of connections to the audio panel (two 44 pin connectors).
Help appreciated. Thanks.

Per the GMA 340 Installation Manual:
J2 connector (rt or passenger side)
Music 1- pin 23 Lt, pin 24 Rt, pin 25 Return
Or
Music 2- pin 26 Lt, pin 27 Rt, pin 28 Return
These are the mini pins, normal D-sub pins are too big. your friendly avionics tech should have some extras, also get him to crimp some short wires to them as its a special crimp tool used.
