4-PIN SWC CABLE
Use the proper 3.5MM to 4-Pin SWC cable for the aftermarket radio you are
using.
OPTION A is used for ALPINE, CLARION, JVC, and KENWOOD units (Blue/Yellow wire
is attached)
OPTION B is used for BLAUPUNKT, BOSS, DUAL, FARENHEIT, JENSEN, POWER ACOUSTIK,
PIONEER, SONY, SOUNDSTREAM and Most Off-Brand Radios.
NOTE: Cap or insulate the 3.5mm plug or Blue/Yellow wire if not being
used. Plug the SWC cable to the ONST-11C module and the 3.5mm plug to the
aftermarket radio SWC port or use the Blue/Yellow wire for JVC and Kenwood
radios.
SELECTING THE AUDIO SYSTEM:
If the vehicle is equipped with an amplified audio system, the ONST-11C has a
built-in audio level adaptor that outputs the proper audio level from the
aftermarket radio to the factory amplifier. To use this feature, plug in the
male 8-pin connector on the ONST-11C harness to the GRAY female 8-pin
connector on the ONST-11C module. The module is also labeled “Bose” and “Non
Bose” to avoid confusion. (see picture below)
If the vehicle is NOT equipped with a factory amplified system, plug in the
male 8-pin connector to the BLACK female 8-pin on the ONST-11C module.
CHIME VOLUME ADJUSTMENT:
The CS-GM11C has a potentiometer to adjust the chime volume. It is set at half
way by default. To adjust the volume, simply use a suitable screw driver and
turn the potentiometer clockwise to increase the volume and counter-clockwise
to decrease the volume.
