Fog Lamp Switch

Hi all, I purchased a Fog Lamp Switch from Moss (162-170).  It came with no
information at all, as I look at the back there are 4 connectors.  2 top, 2
bottom starting numbered at top left with 1, top right 2, Bottom left 3,
bottom right 4.  Can someone clue me in as to what goes to which post.



Moss support said just keep try in combinations until you get what you need.



Can someone show me the light (pun intended)
