will have to wire a relay (shown in Fig. 1 below). If either of the audio sources require fine tuning, there are four separate level
controls on the front of the interface. Plug in the GM24-CARX-AAI’s 12 pin and 24 pin female harness into the factory radio and mount
the interface within the dash of the vehicle with double sided tape or wire ties.
Using the Red/Yellow and Yellow/Red wires

selected by the radio the Red/Yellow wire will provide an accessory output (500mA maximum). An extra relay will be needed for
high current applications. The Yellow/Red wire will provide an accessory output while auxiliary 2 is selected by the radio.
