Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
I need to update the HFS3v3 soon. Meanwhile, you can use the wiring diagram below:

Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
Sorry to bring this back from the dead, but why cut boost and signal ECU? Can the ECU not do both? Just wondering...

It wasn't clear, apologies, it was meant to be either/or.

Re: Subaru WRX to HFS-3 wiring diagrams (2002-2009)
I had a short and an rechecking the wiring. The wiring of this diagram doesnt agree with the WRX ECU. I just measured current on each of the partially pink injector wires and all of them have a (+) signal, while your green wire states that it requires a (-) signal from the injector.
http://www.innovatemotorsports.com/r...ru_Impreza.php This shows the same thing. So is the polarity OK? Because I'm pretty sure most of the WRX if not all Impreza have a common ground and only "speed" (+) outputs to the ECU from their Injectors. |

There is nothing wrong with either diagrams.
