Land Rover have a habit of fitting one wiring loom for all the different models, so you end up with a lot of extra wiring and plugs for kit you don't need. For example an airbag ECU plug in a vehicle that doesn't have airbags, or mine has all the electric window switch plugs in the centre console, even though I've got manual winders.
Wouldn't worry too much about it, if you're really bothered try finding the plug in a wiring diagram in your Haynes manual.
