This is the original OEM workshop manual for the 2017 Subaru WRX and WRX STI repair manual with the wiring diagram in PDF.
The Subaru WRX can trace its lineage back to the mid-1990s with the Impreza WRX, but it became a stand-alone model in 2013. The all-wheel-drive turbocharged four-cylinder is a wolf in four-door sedan clothing and offers a level of performance above other cars at the same price point. For the current generation, Subaru is offering the 2.0-litre turbocharged WRX with a traditional six-speed manual or, for the first time ever, a continuously variable transmission. It’s also offered in a higher spec STi version, powered by a turbocharged 2.5-liter four-cylinder boxer engine.
