This adapter converts the factory Quadlock radio connector in a compatible vehicle to standard ISO power and speaker connectors for an aftermarket stereo.

It is intended for vehicles that do not have a traditional switched 12V ignition supply at the original radio connector because radio switching is controlled through the vehicle’s CANbus system.

• Converts a compatible factory Quadlock plug to standard ISO connectors
• Provides power and speaker connections for an aftermarket radio
• Allows the main factory radio connector to remain uncut
• Includes a loose wire for connection to a switched ignition supply
• Suitable for many European aftermarket car stereos with ISO wiring
• Useful for replacing the original radio in selected PSA-group vehicles
• Simple wiring solution where steering control retention is not required

Many compatible vehicles switch the original radio through CANbus data and therefore do not have a conventional switched 12V ignition feed at the factory radio connector.

The loose ignition wire supplied on this adapter may need connecting to a suitable fused switched 12V supply. This allows the aftermarket radio to switch on and off with the vehicle.

The ignition source must be checked with an appropriate electrical tester before connection. Professional installation is recommended if the correct supply cannot be identified confidently.

Suitable for selected vehicles with the matching factory Quadlock connector and a compatible non-amplified audio system.

Compatibility can vary during a vehicle’s production period. Check the original radio connector, factory audio system and vehicle specification before ordering.

This is a basic power and speaker wiring adapter. It does not retain or provide the following:

• Factory steering wheel audio controls
• Factory radio display or vehicle-menu functions
• CANbus-generated switched ignition
• Factory amplifier integration
• Factory parking sensor tones routed through the original radio
• Vehicle data outputs such as speed pulse, reverse or parking brake

A dedicated vehicle interface may be required if any of these functions need to be retained.

For a compatible plug-and-play solution that generates a switched ignition output from the vehicle’s CANbus data, search the InCarTec website for 20-161-IGN.

The alternative adapter is also intended for vehicles where steering wheel control retention is not required. Always confirm compatibility before ordering.

• 1 x vehicle-specific Quadlock connector
• 1 x standard ISO power connector
• 1 x standard ISO speaker connector
• 1 x loose switched-ignition connection wire

This adapter is intended for compatible non-amplified factory audio systems with a matching Quadlock connector. It may not be suitable for vehicles with a factory amplifier, premium audio system or a different radio connection.

The aftermarket stereo must have compatible ISO power and speaker connections. Some stereos use a manufacturer-specific wiring loom that connects to ISO plugs.

Compare the vehicle connector and original radio system with the product images before ordering. Do not rely on the vehicle model and year alone.
