tucks in like this...just note my top goes down unusually low , so dont let that scare you...but this is how it fits behind the back rest. I have never had any problem with wind picking it up, not even at 110 plus mph.
mine has two snaps ea side abv the arm rests...one facing forward , one inward..
do you have the regular plastic snaps that go over the ss trim for the rest? like these...there you can see the two other snaps that go over the armrest area also
