About: Metra 70-1787 Amplifier Integration Wiring Harness for Select 1986-2005 Audi/Porsche/Volkswagen Vehicles 

Install a new car radio faster with this amplifier integration wiring harness, allowing you to retain your vehicle's factory amplifier. On one side, the wiring harness is color-coded with wires that you'll connect or solder into the aftermarket radio/receiver. The other side has a vehicle-specific adapter that connects directly into the original radio connectors for a quicker installation without having to cut each of the wires. Keep in mind that you may need additional parts to complete your installation, including a dash kit, antenna adapter, and, depending on your vehicle, a special interface adapter to retain audio controls on your steering wheel or other important vehicle functions like navigation, video, and more. 

Specifications: 

  • Amplifier integration wiring harness for fast and easy radio installation
