O2 sensor location.

Hello again, I just wanna know where is the O2 sensor in the 98 Grand Cherokee V8.
I've heard that they have two of them, one is after the catalitic converter but where is the other one. In my wife's car it's right in the manifold but I've been gragging both manifolds but I couldn't find it in mine. Pls your kind help here fellas.
Tks in advance.

Thanks a lot for your help. Believe or not my jeep doesn't had any. Seems that previous owner had an exhaust job and they stick a bolt in the O2 sensor spot.
