A carkit-specific adapter harness may be required for your installation (I have some of these in my booth), or the connections can be made individually. Available on the connection to the carkit is: VBATT - constant +12V power supply Ground - chassis ground Ignition - switched +12V signal Mute - active-low trigger Mute connection Speaker (+) - differential mono audio signal from the carkit or device Speaker (-) - differential mono audio signal from the carkit or device As this harness features ISO connectors, it can be used in combination with Parrot2Car or ISO2CAR vehicle-specific adapters from various suppliers to adapt a bluetooth carkit to certain additional vehicles with factory amplified/premium audio systems. I have a mobile electronics installation business and am selling off some excess inventory. Please feel free to send a message if you have further questions about any of my items. Thanks for looking!
