How do you install a Ox sensor on a 98 Ford F-250 passangerside?

To install an O2 sensor on the passenger side of a 1998 Ford F-250, first ensure the vehicle is cool and disconnect the negative battery terminal. Locate the O2 sensor on the exhaust pipe, typically before the catalytic converter. Use a wrench or O2 sensor socket to unscrew the old sensor, then apply anti-seize compound to the threads of the new sensor and install it by hand. Finally, reconnect the wiring harness and the negative battery terminal.
