Connections to be made
From the 32-pin harness:
• Connect the Yellow wire to the radio's 12-volt battery or memory wire.
• Connect the Black wire to the radio's ground wire.
• Plug the 14-pin harness into the GMOS-09
• The Black/Yellow wire is for the OnStar volume adjustment. This will be discussed in
the OnStar Level Adjustment section of this instruction.
Installing the GMOS-09
• With all connections completed to the aftermarket radio, plug the 24- and 12-pin
harnesses into the vehicles wiring harnesses.
• Reconnect the negative battery terminal.
• Cycle the key, by turning the ignition on for 30 seconds. Then off and on
again to test the radio.
1) Turn the ignition on if not already, and then turn the radio on to verify that the radio
works. Check balance and fader controls for proper operation.
2) Push the OnStar button (if equipped) to verify OnStar is working. The radio will shut off or
mute, depending if the Brown wire on the 16-pin harness is connected, and OnStar will
be heard through the front speakers. Turn off OnStar and the radio will turn back on.
