Default 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
