What wire to use to hook up my Air fuel gauge?

BrysImpreza · 01-08-2004, 11:19 PM

I know Red = 12v switched power
Black = Ground

But having never have owned a turbo car, which O2 sensor do I tap into and does anyone know what wire it is on the ECU?

Thanx!

I can't help you with the FXt,but on the wrx its the rear 02 sensor wire. B17 on the ecu,but Im sure the FXT ecu is different. Can you get a copy of the ecu diagram for the FXT?

I'm sure I can get one, but you telling me which O2 sensor to use I'm one more step in the right direction, thank you!!!
