A PW0 should be an OBD0 B16A. I will check and see if I can find the stuff to jump it to 1 O2 sensor. That header pic isn't right either. If I remember correctly, from the factory the exhaust manifold had an O2 sensor in the 3rd and 4th cylinder primary.

I looked on Hasport's website and found this:

It has instructions for the O2.
