When you look in the type 2 the live and neutral have insulated tips. Hence what you can see in the twizy plug. How complex the solution is depends on how they have wired the Type two. On EVs the Pilot connections are normally linked into the cars charge control system, but to make the charge point come live on the wall, requires some simple components in the plug. Hence how I make type two to 13a adaptors that work.
If this is the case and there is no functional link to the twizy then simply putting Live and neutral (and of course earth) would work. You have to have a type2 wall outlet socket to do this, as the aparently matching inlet to a car (female version) is different and the pins are different lengths. This would mean a box with a wall outlet, cable and your new mains plug.
But a lot of effort to go to just to try it out. (I can supply the parts)
If the twizy type connector two is screwed together then you can see whats inside, take a photo (or two) and let me have them. But a lot of them are moulded so not an option.
