Are this diagrams the same for STI models? Sorry for the ignorance if they are but better safe than sorry.

I am not sure, try matching one of the above ECU physically. The fuel injector wires tend to have a pink trace on it. This will give you a good clue.

Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
Hi, I have a question about 03 usdm, more precisely about amber and white ecu harness connection. If I understand right, I should cut *24 cable from ecu (black&white in my case), connect white cable to part going to ecu and amber to rest? I have HFS-V3, if it's of any importance..

Like to confirm you are referring to the brown cable rather than amber?

Yes, that one. And whole that "CUT&SPLICE" part in red circle on the diagram

Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
OK. it is a white and a brown wire from the grey harness. It is just a relay contact, goes open circuit when failsafe is triggered.
You need to cut the B&W wire in half. Connect the "ECU-side" to the white wire and the "BCV-side" to the brown wire. To avoid CEL, link DR1 on the circuit board

Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
Richard, is this wiring diagrams applicable to the 2013 usdm wrx or did the pinout change at the ECU after 2009?
