Managed to sort mine out finally.
I had followed a guide a couple of years ago where the blue wire from the socket of the valenti is taken out and added to the blue wire for the tail lights. This blue wire is the wire for the normal running condition. The red is the brake.
So I put the blue wire back into the socket:
I then moved the red wire of the bumper light from the red wire of the tail light and moved it to the blue wire instead:
Now this here is the internal wiring I have:
You will need to unsolder the blue wire and the black and orange and solder them all together like so:
Wrap with electrical tape or use heat shrink if you have it.
Now it should function in line with UK law; the fog light will turn on with the fog light switch, the V will work with the normal lights, and the reversing lights working as normal.
I've also added this to that Aussie post.
Hope this helps some people out!
