They get 4 functions out of 3 valves by using each valve for 3 of the functions, and then use 2 valve together for the 4th function...

Up- S3 valve
Down- S1 valve
Angle right- S2 valve
Angle left- S2 AND S3 valve together...

As for a wiring schematic, look at the top of the page, Western is a sponsor here and with a few minutes in their site you will find one.
