Compatibility Notes

  • Audio volume to the amplifier can be adjusted by the dials on the harness.  For easier access we recommend using an external volume knob.(Not included but we can provide one)
  • A variety of wire colors may be used for the remote wire coming off the harness.  Regardless of color, rest assured it is for the remote turn on of an amplifier.
