99 Altima Vacuum line routing

My dad had a super shady shade tree mechanic replace his motor in his old altima. The guys in jail now so it's left to me to finish up. I was chasing a p1105 code and noticed open vacuum line nipples on the map baro switch. So I'm trying to trace all the lines using a diagram from this site and I have a few questions. 1. There is a line, circled in red and I can't tell where it terminates? 2. Also circled in red, the diagram shows two fittings with vacuum lines coming from both. My engine only has one fitting, so I need to know which of the two I have?

The lines circled in red are where I need help
