i've found this easy to do if you;

1) unplug the original sensor connector and let it drop down.
2) unscrew the original sensor and remove.
3) cut the original connector/wire and connect it to the replacement sensor.
4) plug the original connector (now connected to the new sensor) and let the new sensor drop down and hang by the wire.
5) now it should be simple to grab the sensor from the bottom and screw it in.
6) zip-tie/clean up the loose wiring above when done.
