As others said a signal tracer may be the easiest way.

One clue would be if all the wires go through the first box. Normally
they run all the control wires to the first box and then continue on to
the second one. And of course the location of the heads might give you
some clue.

Other alternative is to dig at each head and see what direction the pipe
comes from. That gets tricky too as the pipe from the valve often goes
down the center between the heads and then branches off to each head.

If you have a constant flow of water to a sprinkler head, you should be
able to trace it by sound. Get a piece of pipe and use it like a
stethoscope to trace the water flow, which will certainly lead you to
the control valve.

Simple Find some one or try it your self and witch with coat hangers. Works
for me Some people can do this and some cant.
Bend some coat hangers at a 90 with a 4" handle and use the rest 12" for the
other half . Hold the loosely in your hand out in front of you follow the
line and when they cross you will have a larger obstruction in the area. I
use this to find septic lines gas line ect. Not foolproof but works for me
50% of the time Start at the source by the house

My dad could do that for water!! He claimed it had to be a Willow
stick. He claimed water had to be moving.

So for this job a rain coat and boots will be necessary too!!

I got my degree in Applied Sprinkler Science when hubby was our condo's
building manager. We spent a lot of free time searching for missing
controllers. Start with the non-functioning sprinkler nearest the water
supply line and try tracing it back to the supply. Ours weren't very
deep, so we could dig down to the supply pipe, then follow by line of
sight a few feet, dig again ...

There are instruments for locating them, and a contractor might be able
to do it with ease.
