Hi: The crank sensor is located under the harmonic balancer (the bottom pulley which comes from the engine). All you need to do is unplug the sensor, unbolt it and reverse the process with the new sensor.
If you have other questions or need additional help, let me know.

Do I have to remove the harmonic balancer to replace the sensor

Hi: No, you don't need to remove it. The sensor should be bolted to the block.
