Does anyone know which pin in the ECU is the O2 sensor? I need to know which wire to splice it in to. I dont really want to go direcly to the O2 sensor itself.

 

Cmon someone's gotta know where the O2 sensor wire is on the ECU... i would if i had the manual for my car...

 

Come on..........some one I wanna know too, so I dont have to ask in the future.

but now i dont know which O2 sensor to use???

 

You want the front oxygen sensor. The front O2 sensor is before the cat, and the rear O2 sensor is after the cat.

The rear O2 sensor is for monitoring the cat's performance.

They are sometimes referred to as upstream and downstream.
