As posted by SVXdc

Vehicle Speed Signal (VSS) and reverse gear can both be found in the passenger footwell, in locations similar to those shown here:
Forester 2009 / Impreza 2008 wiring for VSS, Rear Gear and +12V Ignition On
Applies to 2008-2013 WRX and STI, 2008-2011 Impreza, and 2009-2013 Forester

In Impreza/WRX/STI, you can see the connector with the VSS wire without needing to remove any trim panels. Factory wire color is PINK/GREEN.

On 2012-2013 Impreza (not WRX or STI), VSS is pin 19 on the factory 20-pin radio harness. Reverse gear is pin 16 on the 16-pin aux harness. Parking brake is pin 15 on the 16-pin aux harness.

It seems that nearly all recent Subarus have the reverse gear wire in similar spots in both footwells (going to the respective rear light clusters), and the factory wire color is always BROWN/YELLOW.

ADDED: When talking about wire colors, the first color is the main or dominant color of the wire. The second color is the stripe(s). So PINK/GREEN is mostly PINK with GREEN stripes. On factory wiring diagrams, that's shown as PG (no slash).

List of Subaru's abbreviations here (first one I could find quickly. Note that it's not safe to assume BLACK is ground, especially if there is also a stripe).

Factory wires often also have dots. Those are usually not mentioned or documented.
