Glenn, Not all come fitted my 2009 4/4 Sport didn't come with one but the battery was near the back axle on the passenger side. I fitted one as I like the safety of isolating the battery when working on the car and of course it immobilises it.
I think it is the earlier one's that come ready fitted my 1994 had one and my present one has.
I'm pretty sure there are isolaters available that fit directly on the battery terminals for your under bonnet one.
