Crawl under car
Look at rear bumer & you will see 2 white tabs that hold the bumper up - these are held in by poppers - remove poppers & tabs (Possibly screws aswell)
Fold bumper up, You will notice that there are 2 ready drilled holes further up.
Pull black tabs upto meet holes, insert large bolt - Job done
You will notice the hole just to the left of where mine is fitted - this is where the white tabs are attatched (i think thats it its been a while since I did it)
Although if someone fancies going under theyre car tomorrow and taking a photo I'll point out what needs removing
Gives you an idea of what it looks like from under the car
And how it looks from behind
