anybody know-A/F guage install???

[Dudley Dawson]

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!

i forgot that i had posted this thread. i finished installing a week ago. i decided to say f' it and tried the "white" wire. it seems to be working fine. thanks anyway.

what end did you splice the sensor signal too. did you put it in the front or rear.
