NOTE: For Atoto, Blaupunkt, Dual, Farenheit, Power Acoustik, Soundstream, and most o�-brand radios, check the aftermarket radio’s manual to see if the SWC buttons need to be programmed.
4-PIN SWC CABLE
Use the proper 3.5MM to 4-Pin SWC cable for the aftermarket radio you are using.

PIONEER, SONY, SOUNDSTREAM and Most Off-Brand Radios.
NOTE: Cap or insulate the 3.5mm plug or Blue/Yellow wire if not being used.
SELECTING THE AUDIO SYSTEM:
If the vehicle is equipped with an amplified audio system, the SWRGM-48 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 SWRGM-48 harness to the GRAY female 8-pin connector on the SWRGM-48 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 SWRGM-48 module.

For aftermarket radios that have wires for SWC connections, cut off the 3.5mm plug on the Crux SWC Cable (option B) and connect the SWC wires as follows:
Note that there are some radios that only have SWC1 and SWC2, in this case “shield” does not need to be connected.
