Call the sprinkler company that did the work and get a copy of the plans.
If they don't have that, sound very disappointed, say you will send them a diagram of your house and yard and ask for them to draw what they would normally put in a 5 zone system like yours. Better yet, go there when a designer is in.
I wasn't even the original owner but I called the architect 6 years after the house was built and got a copy of the blueprints for the cost of copying them. 10 or 20 dollars. Blueprints. (Of course this was a 109 unit townhouse all with the same blueprints.) They weren't as useful as I thought they would be, so far. But I still think I should have them.)
The whole zone? Won't that be at the water valve and isn't that a known location?
Are you supposed to drain them every winter? Does that mean you know where the far ends are? Open one drain at a time and see which heads are on the same line, because they are the ones that won't have much pressure, or which will stop spraying first when the water turns off. Or disconnect/turn off one zone or all but one zone at the valve, if that is possible (surely it is) and learn which heads are in the same zone that way.
Make a map of all the heads. Color them over with one of 5 different colors. Then draw the simplest 5 lines between them that you can. That'll be it, probably.
