RE:O2 Sensor

[Fast06wrx]

Hi everyon, im new here and i recently purchased a 06 wrx turbo and i was wondering if anyone can tell me what wire from the ecu is the signal wire so i can connect an A/F gauge. Any help would be appreciated.

i had a air/fuel hooked to the factory o2 sensor and it was just a dancing needle, but there are more than one write up on the site

Where?? I hooked up a Apexi turbo timer and its equpipped withe A/F and o2 signal readings and i have to hook it up to the signal wire i just dont know which one it is

[bkotzman00]

i think it is B17 on the ECU, i don't have a wiring diagram handy for you though

Ill try that pin to see if it works. B17, from which connector is it from looking at the ECU, Cause there is four different ones
