Default Ok I need help with manifold hoses please.

Well I am half way done with my Forge FMIC and intake manifold so thas good but I am having real trouble with the hoses that connect to the intake manifold. The instructions they send are not very clear so I am getting confused. What I need to know is which hoses go to the little nipples of the manifold.Also I need to know the names of different hoses. I will post pictures of the ones I need to know.

This is the nipple on the manifold on the opposite side of the TB.

These are two small ones on the bottom of the manifold.

This is the bigger nipple on the bottom of the manifold.

This is the nipple on the TB.





I dont know what this black thing is or what hose connects to it...



I am sorry about so many pictures and all this stuff but if you could help me I would appreciate it more than you can fathom.

lableing as you removed them would of been smart. The one on the end across from the TB is the brake booster, one should go to the dv hardlines. thats all i can think of right now
