I have 5 Nest Thermostats that all have the error "Install Stable Power Source".  That being said I have a TACO ZVC406 Zone Valve Controller which is an older model and doesn't have a "C" wire insert handy.

How would I go about getting power to the Nest Power Connecter in this scenario?

 

@laurentbourg - not sure if you know (thank you in advance)

Each zone on your control panel should have the five wire spots or more. Follow the wiring diagram. My zones did not have a wire in the c spot. That’s ok. Just plug in the wires. You need one power connector for each of the thermostats
