  • Restore a Subaru or Nissan car's factory radio plug that has been damaged or removed

  • Transplant a factory radio into another vehicle

  • Bench test a factory radio

  • Add a subwoofer, Line Output Converter, gauges, or some other accessory to a Subaru or Nissan without cutting or splicing your factory wires (wire together one reverse and one 'forward' harness, and tie into any desired lines).  Or use this 20-pin "breakout" harness.

Although other after-market harness manufacturers make similar reverse harnesses, theirs omit several important wires found on the cars' factory harness.

Fits the factory radios in these models:

  • 2008-2015 WRX / STi (non navigation)
  • 2008-2014 Impreza / OBS (non navigation)
  • 2013-2014 Crosstrek (non navigation)
  • 2009-2015 Forester (non navigation)
  • 2010-2014 Legacy / Liberty / Outback (some; e-mail for details)
  • Many 2007-2016 Nissan

I had these reverse harnesses factory made with all 20 wires.  The wires have the same EIA-standard color-coding used in after-market car audio, with text labels (for example, "Left Front Speaker +"), ready for you to crimp or solder.  Harness includes these wires:

  • Four speakers (8 wires)
  • Ground
  • +12 Volt Accessory (key-switched)
  • +12 Volt Battery (always-on)
  • Power antenna control (remote turn-on for motorized antenna or factory antenna booster amplifier)
  • Illumination ("Illumination +")
  • Dimmer ("Illumination -")
  • Audio Steering Wheel Controls (3 wires)
  • 3 wires for additional signals depending on make/year/model (e.g., CAN bus, VSS, etc.)

Price: $18 each, plus shipping

Don't need all 20 wires?  I can leave off wires your factory radio doesn't use (and will discount the price).  E-mail me to discuss what you need.
