ISO adapter harness for Volkswagen group vehicles with quadlock connectors at the back of the radio.
 
This adapter harness is designed to adapt from the original quadlock style connector in the dashboard to a standard aftermarket ISO connector to allow the fitting of a new radio.
 
This lead has a built in CANbus interface which provides a key present ignition power supply. A key present ignition supply will generate an ignition feed to turn the head unit on with the first position of the key, the interface will continue to give an ignition feed to the radio when the key is turned back to the off position, the ignition feed stops only when the key is then removed from the ignition barrel.
The CANbus interface also generates a speed pulse output, this is used with navigation head units to help the accuracy of the navigation.
 
Plug and play installation.
