I have straight baseboard heatng with a 2 wire thermostat. I need a common. Luckily I have a spare wire. Where do I tie the spare conductor in at the boiler to get common

Post pic of the wires at the boiler you need to put it on the Common of the transformer. Do you have a switching relay box on the wall near the boiler that the wires connect to?
