The 'front' O2 sensor is on the down pipe, the 'rear' is after the CAT.

Both electrical connectors are together, you can see the boxes looking down between the air box and block, close to the firewall. They sit on the tranny.

To disconnect the electrical connection at the coupling, use a small screwdriver and pry the top of the box up. They are stubborn because of grit and dirt, but they will come up about 1/2 inch. At that point, the plug can be pulled out from the bottom of the box.

The O2 sensor can be hard to get out, a 17mm I believe. Best to reach up from underneath.
