CONNECTING THE WIRE HARNESS:
OVERVIEW FOR 24-PIN CONNECTOR
SOOGM-16B
First check that you have the correct SOOGM-16B harness,
each harness is clearly labeled with all information for its
application and wire location. With the help of the wiring dia-
gram join together the SOOGM-16B harness to the new radio
harness you are installing. Start by making all primary power
connections:
GETTING STARTED
Before removing the factory radio check to see if there any
CD’s in the unit and remove them. Now turn on the radio
and listen to check that the speaker fader control is equally
balanced from front to rear, also check the radio display for
the center fader position setting. The Reason for this is that
the digital amplifiers remember the last fader control posi-
tion before the factory radio was removed. Once you have
installed the new head unit you will no longer have fader
control. Once you have completed these steps you now
may remove the factory radio. Also if the vehicle is equipped
with a rear seat audio system this feature will no longer work
with the new head unit. We always recommend disconnect-
ing the negative terminal on the battery for safety also use
towels or a protective blanket around center console to avoid
scratching dash panels.
Yellow (+12v Battery): Constant +12 Volts to the new head
unit.
Red (+12V Acc): Switched Accessory from the key. This out-
put supports up to 1 amp continuous. If you need to use this
output for additional accessories, you will need to use a relay
to prevent damage to the SOOGM-16B. See Relay Wiring
Diagram for details.
APPLICATIONS
16 AND 14-PIN CONNECTORS
FRONT audio inputs:
Gray for right side / White for Left side
CHEVROLET
Black (Ground): To ground wire to new head unit.
Orange/White (Panel Lamp): works in conjunction with the in-
strument panel dimmer switch, this gives full dimmer control
for the new head unit.
2007 - 2010 Cobalt
2007 - 2010 HHR
2008 - 2011 Malibu
REAR audio inputs:
Purple for right side / Green for left side
PONTIAC
2007 - 2010 G5
2007 - 2010 Solstice
Orange (Illumination): Provides illumination with the head
lamp control switch however doses not dim.
Wires with a “Black” trace go to Negative (-) side of speaker
and solid colors goes to Positive (+) side of speaker output
from head unit.
TEST FOR HIGH/LOW SYSTEMS:
You will need to perform this simple test first, to determine
if the audio system is either a “High” or “Low” level output
system. Take the SOOGM-16B module and plug in the
connector harness. Tape off the end of the wires on the har-
ness to avoid any shorting as this could damage the control
module. Now plug in the SOOGM-16B module to the factory
radio harness. On the SOOGM-16B control module set the
rotary switch to “0”. If you disconnected the battery, recon-
nect it. Turn the ignition key to “on” or “Accessory” position.
Find the OnStar button which will be located either on the
swc, or rear view mirror or steering wheel. Push the OnStar
“Phone” Icon button and listen for the OnStar “Greeting”, if
you hear the greeting move the rotary switch to “9” for High
level input. Now press the OnStar “Phone” icon again to exit
OnStar mode. Now turn off the ignition key and again dis-
connect the vehicle’s battery. You will NOT need to perform
the “Setting audio level control” as the module has now been
set to the correct audio input level. If however you hear
nothing at all the system is “Low” level and a speaker level
converter will be needed and you will need to perform the
“Setting audio level control” in this guide.
Blue/White (Amp On): Used for amplifier turn on.
SATURN
USING THE 3.5 STEERING WHEEL CONTROL CABLE
This cable is used on all radios using a 3.5mm remote control
input. Plug this cable in to the port on the back of the radio
labeled for remote. This cable supports Pioneer, Alpine,
Clarion, JVC and Sony radios only no other manufacture is
supported and cable should not be used. This cable is not
needed in vehicles without steering wheel controls.
2007 - 2010 Aura
2007 - 2007 Ion
2007 - 2009 Sky
Blue (Antenna Trigger): Used for power antennas or antenna
amplifier turn on.
Yellow/Black (Park): connect to park break on new head unit
Red/White (Rev.): Connect to reverse wire on new head unit
24-PIN CONNECTOR
CHEVROLET
2005 - 2006 Cobalt
2004 - 2007 Malibu
Red/Black (VSS): Connect to Vehicle speed sense wire on
new head unit.
SETTING THE CONTROLS PRELIMINARY
Once you have made all connections between the SOOGM-
16B harness and radio harness you are ready to plug in all
the connectors. It is adviseable to put down some towels
around the console area to prevent scratching during this
final setup. Start by plugging in the SOOGM-16B harness
in to the control module there are 3 connectors and each
will only fit its given location. Make sure each connector is
firmly pushed in without forcing, as this can damage the pins
on the connector. Now connect the 2 GM connectors on
the SOOGM-16B harness to the factory radio harness that
you unplugged when you removed the factory radio. Again
these plugs will only fit one way, be careful not to force the
connectors. Now set radio down on console and reconnect
the battery on the vehicle not forgetting to tighten down the
terminal.
PONTIAC
2005 - 2009 G6
Lt Blue/Yellow (KW Switch): Use on Kenwood remote radio
control (This wire is also used on new JVC units)
OVERVIEW FOR 14 AND 16-PIN CONNECTOR
USING THE SWC WIRE ON NEW JVC UNITS
New JVC units no longer carry the 3.5mm cable and have
added the SWC signal via a Lt. Blue/Yellow wire.
This wire needs to be connected to the SWC wire labeled
“Kenwood” also Lt. Blue/Yellow. Be sure to keep the dial
switch set to number 4 when using JVC units.
