Cool Multiple Brand Zone Valve wiring

Sorry about the possibly foolish question, but I am new to HVAC, but have a lot of experience with gen. plumbing and electrical work.
I have a 3-zone house. Currently I have 2 taco valves and one Honeywell valve all wired together. The problem is that the circulator is running continuously and I want to make sure that they are all wired together correctly. How should these all be wired? I can only find diagrams for wiring together the same type of valves.
Thanks
Dan

Mixing brands makes a tedious job even worse. The end switch on the Honeywell triggers the circulator. If yours has screw terminals, I think it is terminal 3 & 4. If you take the cover off of the valve, you can see the end switch and where the wires go. On the Taco valves, terminals 2 & 3 go to the end switch. One of the switches must be triggered or the valve is open.
