Can someone please help with these hoses

1 the coolat hose on the back of the motor where dose it go to

2 the 4th vacume hose on the back of the intake



and i also need to find out what to do with the lines that went to the intercooler.

 

1. the one on the upper right, goes to the back of the throttle body.

2. 4th meaning lower? *i think* it goes to the double throttle stuff on the throttle body

 

sorry i should have done this first i have these three hoked up

1 the throttle thing

2 The oil injector line

3 the vac that is on the lower intake between the oil injectors

 

also tth only thing i could find on the back of the throttle is a threaded line is there supposed to be some metal line on it

 

pics!

 

 

 

I found out what i need to do with the 4th vac line. The only place i can find to plug the coolant hose into was the threaded line above the check valve but the threads would keep the line from being water tight. I think i know how to fix it but not sure if this is where it is where the hose plug into
