i depends on if its sensor and bank 1 or sensor and bank 2, sensor and bank 1 is in front of the catalytic converter whereas sensor and bank 2 are behind the catalytic converter. just look for the sensor sticking out of the exaust, disconnect and resolder wiring all you really need is a crescent and a soldering iron. i just went through this with my 2001 Mitsubishi eclipse spyder.
