Connections to be made (cont.) Final Assembly
The following (3) wires are only for multimedia/navigation radios that require these wires.
• Connect the Blue/Pink wire to the VSS/speed sense wire.
• Connect the Green/Purple wire to the reverse wire.
• Connect the Light Green wire to the parking brake wire.
• The Black/Yellow wire is used for OnStar level adjustment for models that do not
come equipped with steering wheel controls. See the OnStar Level Adjustment
section for further instructions.
• Tape off and disregard the Green/Orange wire, it will not be used
in this application
• If retaining the factory AUX-IN jack, connect the Red & White RCA jacks to
the AUX input.
12-pin pre-wired ASWC-1 harness:
•This harness is to be used along with the optional ASWC-1 (not included) to
retain steering wheel audio controls. If the ASWC-1 is not being used, disregard
this harness. If it will be used, please refer to the ASWC-1 instructions for radio
connections and programming.
Note: Disregard the harness that comes with the ASWC-1.
• Connect the Red wire to the accessory wire.
Note: The relay attached to the 3307 harness is only for audible turn signal clicks.
No extra steps are required to retain this, so leave it as-is.
Continue to Final Assembly
With the key in the off position:
1. Connect the 3307 harness into the interface, and then to the vehicle.
2. Locate the factory antenna connector in the dash and complete all necessary
connections to the radio. Metra recommends using the proper mating adapter
from Metra.
3. Before using the kit it must be initialized.
Attention! If the interface loses power for any reason, the following steps will
need to be performed again. Also, if installing an ASWC-1 connect it after you
initialize and test the interface/radio, with the key in the off position.
a. Turn the key (or push-to-start button) to the ignition position and wait until
the radio comes on.
Note: If the radio does not come on within 60 seconds, turn the key to the
off position, disconnect the interface, check all connections, reconnect the
interface, and then try again.
b. Turn the key to the off position, and then to the accessory position.
Test all functions of the installation for proper operation, before
reassembling the dash.

potentiometer clockwise to raise the chime level; counterclockwise to
lower the chime level.
c. When the chime is at a desired level, remove the keys from the ignition.
This will lock the chime volume at its current level.
6. OnStar level adjustment:
a. Press the OnStar button to activate it.
b. While OnStar is speaking, press the VOLUME UP or VOLUME DOWN buttons
on the steering wheel to raise or lower the OnStar level.
