    anybody know-A/F guage install???

    i am installing an air/fuel gauge and i'm having trouble figuring out which wire to tap into at the ECU. i used the Projectwrx.com instructions but his for a '02 wrx. i have a '03. my question is: is the ECU wiring the same for '02 and '03? OR does anybody know a way of finding the correct wire to use for my A/F gauge? a '03 ECU diagram would help. thanks.

    I cant think of any reason the 03 ECU wiring would be different. Did you try the correct wire for the 02? Give it a shot!
