Unplug the wire from the sensor, find the appropriate socket, unbolt the o2 sensor, bolt in new o2 sensor, plug wire onto new sensor, done.

Have you checked the heater? Find the 2 same-color (black?) wires on the sensor itself. Heater should measure 10 to 40 ohms between them. If that's OK, then your problem is wiring in the car.

If you can't get the connector apart, how did you measure the resistance?
There's a latch you have to press, on the side of the plug. Sometimes they get dirty or corroded, & take a fair bit of force to pull apart.
