Plug in electrics

Hi Everybody,
Just got car specific towbar elecs for 2001 v8 disco 7 seater,
Can i find where it plugs into, No
Thought it would be behind the vents either side of rear door, there are two plugs bolted to body but i presume these are earth connections,
If anybody could shed any light that would be ace.
Thanks Clive.

TD5 but presume it will be the same on a petrol one

Remove the offside rear light cluster and the plug is behind there,

Here you go

Cheers Bigeeeee,
