My software says it is located at front center of engine, but doesnt have a pic, sorry. Compare new one to locate it, should be fairly easy

The o2 sensors are easy to pick out, the pre cats are located on the exhaust manifold before the catalytic converter, and the posts are after it, they should be on the side or the top of the exhaust piping, youll see it as it is the only thing that will have wires going to it on the exhuast system.

they sell the wrench or socket at autopart stores nationwide, call them first.
