This allowed me to get the sensor plug/wire through the hole without damaging it, while keeping the hole itself as small as possible. I also added some black general purpose caulking around the hole to seal it up further.

you pushed the plug through the firewall? why not mount the temp sensor first then run the small wires through and keep the hole even smaller? Then you connect the wires into the back of the mirror connector.
