Wiring Harness

The wiring harness will allow to installation of the stereo.

The harness has a built-in CANbus ignition interface for plug and play installation. Also provides illumination.  Use with item 21-120 for antenna FM connection.

This harness adapts from the original ISO and Mini ISO connectors at the back of the head unit to standard aftermarket ISO connectors. The harness has a built-in high to low-level audio adapter to drop the speaker outputs from the new head unit to a low-line level signal to work with the original amplifier in the car. The high-to-low level adapter has 4 dials to individually set the levels of each audio channel to give perfect sound quality.

Aerial Adaptor

An Aerial Adaptor is needed when replacing the original factory-fitted head unit with an aftermarket head unit.  

This cable converts the car's existing ISO aerial plug to an aftermarket DIN type used by most car radio manufacturers. It also provides a power feed to give 12v from the car radio to the car's amplified antenna.

For Alpine Radios use item Connects2 CT27AA04 to convert the DIN end to ISO 

Stereo Removal Keys

Stereo Removal Keys to remove headunit from the fascia cage. Many OEM manufacturers are incorporating special locking mechanisms into their head units in an attempt to prevent stereo theft. This means that to remove one of these units you will require a manufacturer-specific stereo removal key to prevent damage to the head unit or the surrounding fascia and cage.
