Disco 3 towbar electrics

Hi, new to the forum just thought i`d test your knowledge out there!!. Have a 2005 Disco 3 and need to fit the `S` type socket to the towbar, does anybody know where it plugs in and do you know if you still need to run a live feed direct from the battery?? Many thanks in anticipation, Nick.

By the way have owned and driven Landys since i was 17 you still cant beat em`!. Cheers.

if you have nad landys that long then a simple wire job will be easy for you.

Yep, But all the others had not got complicated electrics!!, and i dont want to cause myself loads of agro!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
