Monitor Questions pt. II

I also noticed on the chassis a connection for the yoke.
One of the connections says V.YOKE the other H.YOKE.
Again easy enough to determined that V is for vertical, and H horizontal.
Only thing is I don't know which connection is which!
I know I would require the V.YOKE to be connected as my monitor orientation is
vertical. However I'm unsure if the V.YOKE connection is the connection below the
typing V.YOKE or if it's the one above the typing V.YOKE
