im installing my O2 sensors right now, and i cant find where the upstream passenger one connects to, when i took out the old one it wasnt even connected.Th drivers upstream sensor is behind the engine by the fire wall on top. does anybody know where the 2nd oxygen sensor connects to?
thanks all help is apreciated

 

on top of the transmission housing, if you look behind the engine from the top you see a small space between the engine and the firewall, down in that space you can see the transmission and the connector, not too bad to reach but very difficult to unplug!

 

thanks got it
