The four rectangles along the bottom are the four NPP valve connector pinouts. Two on the left are for the AFM valves, two on the right are for the loudness control.
FYI, If you are just thinking you can put a switch with a hot lead to open and close them, it won't work. You need a specific PWM signal from the controller. You could switch the valves from "working" to "not working" by opening the hot lead, but that is it (so if they were closed when you switched it, they would stay closed, and visa versa). -Geoff
