Mmk I'm having some trouble with my first KA-T Project, I'm new to turbos so try not to bash too much

this is the problem that I have. On the turbo, I know of two oil lines, there is one big one at the bottom that bolts up the the underside of the turbo, the second is at the top side of the turbo. Those are the only two that I have on the car so far. My question is what are the oil fittings that are circled in red in the picture?? And also where do they conect to?? Any help is appriciated.
