To get the sensor out of the exhaust manifold. You want to get an offset 22mm socket. Be sure to spray the sensor with some penetrating oil and let it work for awhile.
 
Thanks guys. Just didn't crawl deep enough nor expect to see it there.

Now to wire the wideband correctly...
 
The WB02 needs to be installed a ways away from the exhaust manifold, or it will overheat. Check the WB02 instructions, but 1 to 2 feet should be good. If you still have the catted downpipe, it needs to be before the cat. The bung in the bend of the pipe is too small for a WB02 - it's for an exhaust gas analyzer. You may need to add a bung. It's also probably better to keep the narrow band O2 for K-Jet and just run the gauge on the WB02.
