Applications:

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

• Retain use of your car's audio Steering Wheel Controls (interface adapter module required for most head units. I also have the Axxess ASWC interface available. See this page for more info).

• Note: If you want to keep your factory HU and add 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, see this combined 20-pin forward/reverse harness.

• For older model years and 2008-2012 Imprezas and Foresters with OEM Kenwood or TomTom navigation, please see this 14-pin wiring adapter.  Ask me about a 24-pin harness to retain your SWCs, aux, etc.

Harnesses from other after-market manufacturers omit wires for the Steering Wheel Audio Controls.  Some have even omitted the ground, power antenna, 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 printed 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 (for special projects, or when you're keeping your factory radio and adding an amplifier, subwoofer, gauges, or other accessories):

• CAN data bus (2 wires)
• Illumination (–) for custom lighting projects (Note: aftermarket HUs do NOT need this — use the "Illumination +" wire that I include standard)
• VSS (Vehicle Speed Signal) — present on the factory harness on some 2012–up Impreza and Crosstrek models

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