Now referring to this picture I updated. I'm quite positive the boost line is the one circled in green. Although it's not capped off on it's own, it looks just like the same line I've seen everyone else reference to. And the second connection, circled in yellow I followed that line and it connects to the bottom area of the throttle body.

If I was to connect the boost gauge into the boost line circled in green. What then will I do with the connection circled in yellow? Do I cap that off? Or as I mentioned in my first post, could I "T" in between the two lines.

Thanks, I appreciate everyone's help.
