underneath the rear antiroll bar you will find two plastic hooks. Remove those. Two of the brackets attach there. The other two you need to remove the mat. Attach the brackets to the holes which run along the width of the boot. You then need to cut two small slits in the boot mat for the brackets to poke through. Think the smaller brackets go on the bottom and the long ones on top. Sorry can't be much more help. If you are still struggling I'll take some piccies of mine.
