Wiring for Zone Control Valves

I'm removing my boiler. The system has three zone control valves. I was careful to label everything.

But alas, I was not careful enough.

Each valve has a pair of yellow wires and a pair of red wires. If I knew what their internal hookup was I could wire them correctly to the other wires in the system. How can I find out what the wires go to internally?

See an image here:

If you go to this web site and scroll to the wiring diagrams you will find the diagram you are looking for. You may not have a Burnham boiler but the zone valve wiring does not change
