Once you have all this ready, you can begin the process to install your Google Nest thermostat.

If you have an old thermostat still in place, remove it from the wires. Keep in mind where each wire is connected, so don’t cross wires into the wrong terminal. Crossing wires can cause everything to go haywire or ruin your thermostat.
You should be able just to insert the wires into each terminal. You can use wire cutters to shorten the wires if need be, but this is optional.
Next, you will want to insert the C-wire adapter wires. This will be a little different since you don’t have a C-wire to connect to your thermostat. Take the two wires from the adapter and insert one into the Rh terminal for power. Then take the second wire and put it in the C terminal.
