My engine threw a code and I'm going to replace the ECT sensor. I've searched around the inside of my car and watched a few videos, etc, but surprisingly can't find a lot of specific information on its location.

They hid it in plain sight. Pop the plastic cover off over the ignition coils, right between cylinders 2 and 3 is the temp sensor under the rubber cover. The new one gets torqued to 106 Inch pounds.
