PAC AAI-GM24 Auxilary Input Problem - Need help!

[Klaus]

Which version do you have? There appears to be two versions of the adapter.

One with 12 and 24 pin connectors (older version):

Newer version, 12 pin connectors only:

If you have the newer version, did you connect the yellow and black wires? Yellow needs constant 12v, and black is ground.

You will probably not use the Red and Orange wires, so they can be taped up and tied out of the way.
