This damn C wire. Where can it go on my setup.

I've researched what I can, but apparently have failed, I have a spare wire but have no idea where to put it on my setup.

I've got a volt meter, just not sure where to check in this cluster.

Trying to set this up so I can use redlink devices (primarily separate temp sensor)

Help if appreciated, photos will be linked shortly.
