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.
