The fuse for the O2 sensors is the ENG-1 fuse in the I/P fuse block, here is the wring diagram.

I do not need the wiring diagram ... I do need to know the exact location of the fuses in the fuse block ...

I always include wiring diagrams incase I need to look at them. That way they are already here. There is only one fuse, the ENG-1. I'll see if I can download the owners manual.
