Hello..
From what I know the pickups should be parallel to the bridge and vertical to the strings,that is the position I know with Les Paul pickups.You should have two of them and each should have sox screws on it(these six should be crossing almost exactly above of your strings)and other six screws on the "frame" of the pickups,three on each side.Anyway,it should look like this:

I hope this helps...
