Hella fuse blowing

alright so i am following the diagram to wire up my hellas...everytime i put the glass 30A fuse into the little holder i flip the switch and the fuse instantly blows....anybody have an idea wtf is going on with it? i have the lights grounded the switch provided is grounded.... one wire going from switch to battery for switch power....and other from battery to relay for power. im using that switch and relay that comes with the hella 500s. the switch has three prongs.
one yellow wire going from switch to relay, one green wire going from battery to switch (switch power), one blue wire from switch to seat (ground)

in the diagram that pretty much everyone has, (not hella one) it shows only two wires going to the switch....should i splice the green wire that gives the switch power to the wire that goes from the battery to the relay? or do i need a two prong switch?

any help?
