Default Re: Subaru STi to HFS-3 wiring diagrams (2004-2013)
I have a factory service manual for my 2013 WRX. I am having issues finding a break down of the wiring connectors for the ECU. There is however pictures of the pins of the 4 connectors and they seem to match the 2013 STI. Do you know if the 2013 STI wiring diagram here will work for the 2013 WRX? I will be purchasing the HFS-3 soon to install in this car. Any info would be greatly appreciated, thank you!
