3-phase version has part number EP2CCU1130A
Connector part numbers are HVC5P63FSX06 (input) and HVC2P28FSX04 (output) but they seem unobtanium.
UPDATE: found them on ebay https://www.ebay.de/itm/405268426335
The logic connector 72952-0200 can be had from ali https://de.aliexpress.com/item/1005006313777789.html and https://www.ebay.de/itm/356037510286
Rather pricey and you have to buy multiples but at least there are many offers now.
Damien has gathered some info here: https://github.com/damienmaguire/MG-EV-Charger (V2L pinout is the one you want)
And in this video
I tied both CAN busses together, as Damien suggests.
Once 12V is supplied to 4G (GND) and 1H the charger powers up and pulls around 800mA. After a few seconds it goes to sleep. It can then we woken up with pin 3D. If 3D and 1H are tied together on startup the charger pulls more than 2A (current limit kicked in). When connecting 3D to 12V via 10k there is no problem.
That's how far I've come, might just wait for Damien to do the rest and then steal it
