C-wire how to install in steam boiler

[monserate123]

I would like to install the c-wire in steam boiler. I have the kit  to install c-wire but don’t know where other two wires are install steam boiler

Is this for the Nest with the mirror glass front and only one R terminal, or do you have the Nest Learning model with Rh and Rc terminals on the base?

Take a pic of the old wiring on the thermostat and also the wiring at the boiler showing where the wires are connected.

Typically when working with a boiler of any type, you will need an external 24Vac transformer and will have to do a little custom wiring. 

Here is an example of how you'll need to wire it up.
