http://ift.tt/2gNAmkd have two furnce units. My other unit is the same except the red is in the Y and the white is in the C. I was trying to install the ecobee power extender since my thermostats don't have a blue wire (i've checked both thermostats). But as you can see, there is a wire in the C terminals.I can't plug both wires into the extender, it only accepts one wire. I don't know what to do with the extra wires in relation to installing this power extender. Any help? via /r/DIY http://ift.tt/2vOPt3l
