im talking about that gold-colored nipple looking-like thing pointing towards the turbo. it seems to be coming out of my transmission. i forgot whether i had disconnected it or not. should i be worried?

 

That is the nipple to bleed the Slave Cylinder.

 

is it supposed to be like that? or do i gotta plug it up or connect it to something?

 

It is just supposed to be like that, actually, there might be a rubber cap for it.

 

You could put a rubber dust cap on it. I had one, but mine fell off somewhere.
