Wyze Thermostat No control board

Hey everyone! I just purchased the Wyze thermostat and was confused as there is no control board. I was wondering if anyone could give me a hand, This is what I’m working with. Thanks in advance.

Install the C adapter at the wire splice point in this picture.

In your photo, the wires coming from the top go to the thermostat, the wires coming from the bottom go to the A/C compressor, and the wires coming from the right side go to the furnace.

Make sure the furnace power is off while adding the C adapter or you will need to replace the fuse in the furnace.

Thank you! I finally got to do it and it worked! i did it at the splice where suggested. The whole thing took about 20 min including all the wyze updates.
