Which ECU to use?

I might have fried the ECU on my 2002 WRX.

 

Wondering two things:

 

1 - which ECU's are interchangeable. 2003 Impreza? Found a cheap ECU in scrap yard. Turbo car vs non make a difference? I know the tranny doesn't make any.

 

2 - Trying to find the right fuse/ fuses? to the ECU. Just in case the problem is that simple.  anybody know any systems that are run by the ECU that I could test to see if they work with the key on?

 

Thank you all... always great help!

 

1000 heads are better than one..

2002-2003 WRX only. 2004-2005 will work but you may have ghost codes for equipment that is not there or coded differently.
