4-PIN SWC CABLE

Use the proper 3.SMM 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-11B 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-11B 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-11B harness to the GRAY female 8-pin connector on the ONST-11B 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-11 B module.

CHIME VOLUME ADJUSTMENT

The ONST-11 B 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.
