This adaptor is required to replace factory fitted radio with an aftermarket headunit (Alpine, Pioneer, Kenwood, Sony, JVC etc.). It will convert the car original power and speakers wiring connector to a standard ISO connector. Simply plug one end of the adaptor into your cars wiring harness, and the other end into your new radio, without the need of tools or cutting of wires.

Harness adaptors connect the head unit to the original radio connector without the need to cut any of the existing wiring.

Compatible with following vehicles:

Car Make / Model	Year	Remarks
Audi A3	2005 - 2012	All models with Fakra connector and half amplified Bose system Connection: Quadlock (Fakra)
Audi A4	2005 - 2015
Audi A6	2004 - 2011
Audi TT	2006 - 2014

Note: ISO Harness Adaptor For All models with Fakra connector and half amplified Bose system.

Please Note:

• When connected your new stereo may not power up, and this is no fault of the wiring harness purchased.
• Audi / VW / Skoda / Fiat and other vehicles tend not to have an ignition switched live feed.
• In these cases it is necessary to manually connect a spurred live feed from fuse box for example to feed switched power so the new stereo turns on and off with the key.
• The wire in particular on the new wiring harness will be the red wire.

IMPORTANT NOTE: Please make sure that is the correct Wiring Harness for your car by firstly checking to see if your make, model and year of car is listed in the advert. Secondly by checking to see if the connection in the picture listed is the same as you have in your vehicle.
