Physically, the 4 way could go anywhere. Electrically, it's located between
two 3 way switches. When you install a pair of 3 way switches, Three wires
are run between them, two of those wires are called travelers, and get
connected to the 3 way switches on the terminals other than the common
terminal. When you install one or a hundred 4 way switches into the circuit,
they simply go between the travelers, so you're cutting the travelers giving
you 4 wires, two from one side go to the input and two from the other side
go to the output

HI "S. Barker",

When you say "...WHERE the 4-way is is anybody's guess..." are you
saying it doesn't matter if the 4-way switch is installed at either
end of the hallway or at the intersection of the legs?
