2 wire honeywell zone valves

[BOILERMAN]

i have 2 red wires and 2 yellow wires . Where do i hook them up on the boiler ?

The two red wires are connected to an end line switch, which closes when the valve is fully opened. Those two wires close a low voltage circuit to start the circulator. The two yellow wires are the valve's motor. One of them gets connected to one leg of your 24 volt transformer, the other one gets connected to the return wire from its thermostat, the second wire from the thermostat and the second leg of the transformer get wire nutted together. Since you have two zone valves, just duplicate the process

Wait a minute.....Your name is BOILERMAN and you don't know how to connect up a zone value? You should call someone who will connect the valve up correctly.
