Bank one is the rear bank on this, if you go down over the rear cam cover about where the secondary air valve is, it threads into the top of the manifold. You will probably need a crowfoot, and possibly a universal extension. The sensor connector is clipped to the same bracket as the secondary air check valve.

Hey Factoryjack, do you have a picture of the bank 1 sensor 1 from the top / boottom. Whats a crowfoot?

A crowfoot is basically, an end wrench, made to go on the end of an extension, working from the side like a wrench, in a space suited for a socket. Here is a picture.
