Trying to install my Wyze thermostat. Here is a pic of the thermostat with the Rc, Rh, G, W, and Y wires

 ![image](https://us1.discourse-cdn.com/wyze/original/3X/d/b/db4e60a24ea30e113d5f3cb1d8909d921ef41299.jpeg)

The control board inside the unit has the red and yellow wires at Y, green and black at G, white and black at C, and blue at R. To complicate it further, wires appear to be sliced to different colors outside the unit, but I think I can match them. (Pic 2 comment)

The furnace is a Old Honeywell with no obvious model number, but a couple pics of model numbers, wiring, and inside. (Pics 3-5)

The white and red wires that go to the splice point come from here, not the main control panel with the letters. (Pic 6)

I’d appreciate help if anyone knows,  
Thanks!!
