I went through the installation and it was determined that I need to install the wire… I had a nest and did not need to do this part. The instructions are pretty straight forward however, when looking at the wires I need to disconnect from the board and connect on the c wire, my Y connector on the board has a yellow and a red wire connected to it. Do I just remove the yellow wire an connect that to the c wire? Or is my furnace not comparable? Thanks in advance for any help!
