C Wire for steam boiler

[Golfdesign84]

Trying to wire a nest thermostat to a 2-wire steam boiler. From everything I’ve read I need a C wire. My thermostat wire is actually a 3-wire with the third wire unused so I have a spare wire, just not sure where to terminate it at the boiler. Has anyone been successful getting the Neat to work with a steam boiler?
