Plug-In Harness for OEM Radio

The Metra 71-9003 is a 40-pin reverse wiring harness that plugs directly into the factory radio connector in listed BMW, Volkswagen, Mini, Dodge, Pontiac and Saturn models. It provides power and four speaker connections without cutting the original loom. Installers working on a 3 Series, Golf, Jetta, Passat or Touareg from the early 2000s can retain the vehicle wiring integrity while fitting an aftermarket head unit.

Fitment Across Multiple Brands

The harness covers a wide model range including 3 Series 2002-2005, 5 Series 2002-2003, X5 2000-2006, Golf 2002-2006 and 2010-2011, Jetta 2002-2011, Passat 2002-2011, GTI 2002-2011, Beetle 2012, CC 2009-2011, Eos 2007-2011, Tiguan 2009-2011, Mini Cooper 2002-2008, Dodge Sprinter 2008-2009, Pontiac G8 2008-2009 and Saturn Astra 2008-2009. It frees the installer from sourcing individual pins or depinning the factory plug.

40-Pin Connector Capacity

The single 40-pin connector carries all required power and four speaker circuits for the supported vehicles. It handles the factory wiring layout for the listed model years up to 2012. Builders needing connections for additional amplifiers, steering-wheel controls or data buses will require separate adapters not included with this harness.
