Hoses near IAC/Throttle body

[SunRa67 2]

HI there, Im looking for some advice on what the hoses here are supposed to connect to? 

 

The engine is a XU10J2: 

- The Red one is currently source of a big vacuum leak and the engine stalls when I place my finger over 

- The green one is also a vacuum leak source but less so, when i place my finger over it nothing much happens but I can feel a small amount of suction

 

I tried blanking them and it starts better but stalls when up to temperature and revved. 

 

Any information on where either hose is meant to go would be super helpful! P.s. I am fairly new to all of this so please be kind, I may have some silly questions
