WRX Wiring Diagram
 

Does anyone have a wiring diagram for a '01 WRX ? I need to find the injector pins (to connect FiA2) without blowing up my ECU - any ideas ?

Wiring diagram
 

In case anyone else is interested, I got this off the North American Subaru Impreza Owners Group (NASIOG).

The RED wire from the FiA2 must go to a 12V source - this can be direct to the battery if you want - but the ignition swith on the ECU is fine. (Pin A5 - Green with Red stripe).

The GREEN wire from the FiA2 must go to the switched ground of any injector from the ECU. (Pin D1 - Pink).

I have checked and there is no inline load resistor on our cars as we have high impedance injectors (a whole 13 ohms!!) - so that other info is not an issue.

Richard was a great help and has answered my emails late at night his time. True customer support.

I will be doing exactly this install tomorrow and let you know how it goes. Cheers,

Andrew

I have the following diagrams, not sure if this applies to your WRX.
