Radio Wiring Adapter (Harness)
 for the Subaru WRX

Also fits all other 1995-2007 Subarus
(Impreza, Forester, Legacy, Outback, Baja, Tribeca)
Also fits some 1993-1994 and some 2008-up models (e-mail for details)

Allows you to install a new, after-market radio in your WRX
without cutting or splicing any factory wires!



  • Install an after-market head unit in the WRX (and all other 1995-2007 Subarus besides the SVX).

  • Install a subwoofer, Line Output Converter, or gauges in the WRX or other late-model Subarus without cutting your factory wires (connect one reverse and one 'forward' harness together, and tap off from any desired lines).

  • Does NOT fit the SVX (see this SVX wiring adapter).

Although other after-market harness manufacturers have these (Scosche, part number SU03, and Metra, part number 70-8901), theirs lack the Orange/White dimmer wire.  Subaru factory radios require this wire for the illumination to work.  I started making these mainly for WRX owners who are keeping their factory radio and want to buy both a reverse and forward harness at the same time and be certain they get harnesses with all 14 wires.  Note: The dimmer wire is not needed by most after-market radios.

The wires 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.  The 14 wires are:

  • Four speakers (8 wires)
  • Ground
  • +12 Volt Accessory (switched)
  • +12 Volt Memory (always-on)
  • Power antenna control (remote turn-on for motorized antenna or antenna amplifier)
  • Illumination ("Illumination +")
  • Dimmer ("Illumination -")

Price: $12 each, plus shipping

I also produce a  reverse WRX harness, also guaranteed to have all 14 wires.
Order at the same time to save on shipping.
