Turbocharge boost control solenoid valve

hi all,

Does anyone have a simple diagram (a novice can understand) of where the three pipes coming from the turbo control solenoid contect to please? Reason for asking is because I have just got the car and replacing the valve but on looking at the car I can’t find the turbo air filter and someone has blanked off one of the pipes coming from the valve currently on the car. Cheers
