Applications:

• Install an after-market head unit in the 2008-up Impreza/WRX/STI and  2009-up Forester (without OEM Kenwood Navi), and all 2010-up Legacy/Liberty/Outback.

• Retain use of your car's audio Steering Wheel Controls (interface adapter module required for most head units. I now have the Axxess ASWC interface available. E-mail me for details).

• See this combined 20-pin forward/reverse harness to install a subwoofer, speaker amplifier, Line Output Converter (LOC), audio processor, gauges, phone car kit, or any other application where you need to tap off or connect between wires on the radio harness.

• For older model years and 2008-2011 Imprezas and Foresters with OEM Kenwood Navi, please see this 14-pin wiring adapter.

Harnesses from other after-market manufacturers omit wires for the Steering Wheel Audio Controls.  Some even omit the ground and illumination wires. My harness avoids needing to tap into factory wires (the reason you use this kind of harness in the first place).

The wires on my harness have the same EIA-standard color-coding as other after-market harnesses, with text labels (for example, "Left Front Speaker +") and pre-stripped ends ready for you to crimp or solder to the harness that comes with your new radio. All harnesses include:

• Four speakers (8 wires)
• Ground (includes second branch with screw-terminal lug)
• +12 Volt Accessory (key-switched)
• +12 Volt Memory/Battery (always-on)
• Power antenna control (remote turn-on for motorized antenna or antenna booster amplifier)
• Illumination ("Illumination +") — used for dimming on many aftermarket HUs
  
• Audio Steering Wheel Controls (2 wires)

Optionally add this additional wire:

• 3rd Steering Wheel Control wire (for models with phone/Bluetooth buttons on steering wheel)

Ask me about including these additional wires (when keeping your factory radio and adding an amplifier, subwoofer, gauges, or other accessories):

• CAN data bus (2 wires)
  
• Dimmer ("Illumination –") — NOT needed for aftermarket HUs
  

See my Subaru 20-pin pin-out table for more information about the factory wires.
