With the faceplate now gone you can see in what locations these wires go. You can remove each wire and tag each wire with its name i.e. RC, RH Y1 and so on. Or you could simply take a picture of the wires and use it later when installing the ecobee. If you have a jumper cable like I do in from RC to RH ignore this as your ecobee will not need a jumper. Simply focus on the wires coming from the wall.

Now that you have removed the 2 screws. Pull the wires through the hole and remove the old backplate.
Step 14: Installing New Backplate
Find the new backplate and place it up to where the old plate used to be. If you have no damage you can use this plate as is. Mark the wall where your 2 new holes are going to be.
Step 15: Drilling the Holes for the New Backplate
Use a power drill to make the 2 new holes for you.
