Fieldsheer luggage help!

hey all. i just purchased some field sheer expandable saddle bags on sale at the local shop, but they didnt come with any instructions! it should be simple. there are two large velcro straps that obviosly go across the seat, and lots of other buckles that dont seem to match up to well. i cant imagine the velcro aross the top of the seat being the only things to hold them on. so before i went and lost them off my bike i thought i would see if anyone had some helpful tips or pics they could send my way. thanks! and be safe.

 

I don't what the Fieldsheer bags look like, but my Cortechs have four short straps in addition to the over-seat straps. I mounted two U bolts to the rear fender for the rear straps, and the passenger peg brackets, right in front of the pegs, work for the two front straps.
