First remove the rear bumper 4 bolts on back and 2 small bots at the side top and remove the rear inner trim.

next remove the towing eye on the offside 4 bolts looks a bit dirty on the pic


Attach the mounting plate on the near side with bolts provided holes already there

next offer up tow bar and realise spare wheel is in the way so remove that too
offer up towbar and secure to toweye bolt holes and mounting plate loosly to begin with
Drill up through support bar with long drill bit then from the top open up the hole to allow spacer bar to be put in place

and secure with long bolt and washer
put bar with nut on in gap by towing eye section and secure with bolt

Tighten up all bolts to required tourque and refit trim spare wheel and bumper
then attach towball and cover

quite easy to do, specialist tool required are long drill bit for the spacer and a hole opener but a file wil do I suppose
And a tourque wrench,
The electrics were done after and were easy as well as instructions are with the kit.
I hope this helps any one thinking of getting a towbar.
I found no real problems
