Sadly I now think it may be impossible or very difficult to modify my car so it can use a variable or reduced Amp EVSE.coulomb wrote: ↑Mon, 04 May 2020, 20:27
Edit: the pilot processing hardware may be missing from the 2011 chargers, but then how can that mob offer a harness that fixes the problem?
Edit 2: you may also have to add the beige / pink / violet wire or parts thereof to the EV-ECU,

I did some more digging but did not unearth any useful nuggets.
I tried to find out where the signal wires from the inlet socket go .
This is a picture of the GS1011 (9499 A698) from GELCOservices (with my explanatory text added). The one in my car has the identical part numbers, made in Japan.
[ Edited Coulomb: removed copyrighted image. Unfortunately, it's about the only image on the internet of this harness (modified or factory original). ]
From the inlet port the wires go to a bridging plug on the harness incorporating a 2.7k Ω resistor.
[ Edited Coulomb: see this post (2 posts down) re the presence of this resistor near all J1772 inlets. ]
Then they plug in to the main loom forward (probably to the EV-ECU but I could not accurately identify the pink and aqua wires there,too many wires!), but they definitely do not go to the charger (E-03 pin 9).
