Okay, so the part numbers for the towbar are: Witter VW43C and Witter Quantum Upgrade ZQ3012.
The
guide I used to fit my towbar can be found at

It is an excellent
guide; thanks to Simon fo creating it!
The only additional information you will need is:
When you mount the side arms for the main cross bar, there are 2 sets of holes. You need to mount them so the cross bar is furthest from the car.
The electrics: I used a bit of trial and error but now have a fully working trailer board; the colour wires i have matched are as below: (the first refers to the wires coming from the electric socket/buzzer.
Orange – White&Black on LH Cluster
Black – Grey&Black on LH Cluster
Brown – Grey&Red on Wires along boot top
White – Brown on Wires along boot top
Red – Red&Black on Wires along boot top
Blue – Grey&White on Wires along boot top (this was present on my 1.4s but not my LCR)
Grey – Green&Black on Wires along boot top
I removed a small area of insulation and then soldered the wires in, and taped them up.
This finished item looks as below:
