I've just done this, hope it helps someone else as I'm pretty chuffed with it.
I didn't want to chop into my wiring loom to wire in the towbar wiring, as it's tight in there with the furniture fitted, and also I'm chicken! So I've managed to get the correct feeds from the following places.
White (earth) crimped on a ring and bolted it to the chassis earthing point by the rear right light cluster
Blue (fogs) I acquired a lighting loom from a scrapped van, and cut out the single brown plug from the loom which is the fog light plug. I unplugged the 2 halves and joined the wires back together with bullet connectors including an extra wire in one of the bullets to connect the blue wire to. I just unplugged the original fog light plug and plugged this one into both halves.
That's the hard bit done now, the rest went onto the rear right light cluster, see photo below.
Green (RH Indicator) Large spade connector onto the 2 pin vertical socket, bottom pin
Brown (RH Tail Light) Large spade connector onto the 2 pin vertical socket, top pin
Red (Brakes) Small spade connector onto the horizontal 2 pin socket, Right hand pin
Yellow (LH Indicator) Small spade connector onto the 3 pin horizontal socket, Left hand pin
Black (LH Tail Light) Small spade connector onto the 3 pin horizontal socket, Middle pin
Just need to make sure the pins are shielded from each other, either with shielded spades or by taping round the spade.
