Adding C wire to WiFi thermostat

Question

I’m trying to add c wire to furnace to run a WiFi thermostat but don’t know where to hook up c wire to get power to turn on thermostat i have 2 extra wires just don’t know where to put one them to get power

Answer 1

Look for the junction of brown wires and attach your C wire to that

On the wiring diagram for your furnace, the brown wires are all C wires, and they come together at a junction that should be somewhere near where the mains wires come in. Connect your C wire (which can be any unused wire in the thermostat cable) to that junction, perhaps with a length of extension wire (brown stranded #14 THHN/AWM will do the trick), and you'll be good to go.
