Installing Thermostat in old Carrier A/C

Hey guys im trying to install the wyze thermostat to this setup but im lost.
My panel have this letters:

The actual thermostat is connected

The blue cable coming from the panel is connected to the C but in the thermostat is connected to a red wire coming down from other white and red cable.

This is the original layout

Any suggestions?
I’ll appreciate, thanks

This is how is connected

This is the panel:

There’s no Y wire connection

That’s an interesting way to do it… Well, you have a C at the thermostat, so no need for a C adapter. just pull slightly on that blue wire that runs into the wall and you should find it wire-nutted to the red wire that goes into the wire loom with the white wire that goes to Y. you’ll want to get a short scrap of wire and add it to that wirenut, with the other end going to C on your wyze thermostat.

In the following diagram, the new wire is marked in grey.
