Disconnect neg terminal of battery, unplug o2 sensor, unscrew o2 sensor, screw new one in, plug new one in. Repeat

recommend getting the exhaust system hot before you try to remove it, and purchase or rent an o2 wrench, makes the job a whole lot easier

After I disconnected the o2 sensor, I just cut the wire to put a socket on it since I was gonna throw it away anyways...

Look right under you engine and right after your catalytic converter in the exhaust pipe. Should be a sensor just sticking out of there
