Forester Radio Connector Pin-out

The table below was compiled from all of the Subaru radio wiring diagrams from 1993-2007 (2008 continues to use this pin-out, but I have not been able to look up the factory wire colors on that year). Model years 2009-2010 with Navigation also use the same connector and pin-out shown here.

2009-2010 non-Navigation radios have changed to a new 20-pin connector. See this pin-out.

All Subarus since 1993 (except for the SVX and North American Legacies 1993-1994) have used this same 14-pin connector and the same pin-out.  A few of the wire colors in the cars have changed over the years, but the functions of the pins have remained the same.  The table below shows the wire colors for just the Forester.  (Here are similar tables for Impreza/WRX and Legacy/Outback)

Pin numbers on shellThe pin numbers may be stamped on the sides of the connectors, on the hinged flaps at the rear that lock in the wires.  The numbers are very hard to read until you hold the connector at just the right angle in the light.


When two colors are listed, the first is the main color and the second is the stripe color (main/stripe).


"NC" means there is no metal contact at that position in the connector shell (and thus no wire).


Column "A" lists the wires on the Radio Connector in the Forester.  This is the plug whose wires disappear behind the dash and go to the speakers, etc.

e. Column "B" lists the wires on the Forester Reverse and Forward Harnesses.  These are the EIA standard wire colors, used by after-market receiver and wiring adaptor manufacturers.  Use this column to verify that the adaptor was assembled correctly.

When installing a Forester radio in an SVX:  Crimp or solder the wires in column B to the same colors on an SVX wiring adaptor.

In the Forester:

  • If restoring a damaged or missing radio connector: crimp or solder a reverse harness (wire colors in column B) to the car's corresponding wires (colors in column A).
  • If installing a subwoofer or Line Output Converter (LOC): crimp or solder a reverse harness (wires in column B) to the same colors on a Forester 'forward' harness, and also connect the desired speaker wires to the sub or LOC.
f. If you're working with the Forester wires (column A), note that there are complimentary pairs (e.g., a Red/Black and a Black/Red).  Don't get these mixed up!  The stripe color is thinner than the main color.  There are also duplicated colors (e.g., Blue/Red).  It helps to work in bright light.
g. There are two pins related to dash illumination -- 1 and 7.  For the Forester radio's illumination to work correctly in an SVX, connect pin 1 to the SVX harness' Illumination wire (pin 4), and connect Forester pin 7 to the SVX's Dimmer wire (pin 13).

Note: Although these harnesses are referred to as "WRX" they have exactly the same pin-out as the Forester.
