All of the wiring diagrams I can find online only show five wires.
Pilot/Proximity (I've identified those).
Ground and the two hot (I've identified thoese).
But they don't have two other wires connected to the ground wire anywhere.
Are you saying that the two smaller green wires that are connected to
the large green wire are part of a isolation ground circuit?

Just type in your search engine - J1772 wiring diagram and you will see

I am using a industrial 5 wire receptacle and plug in my EV that has a
extra isolation ground circuit. A isolation ground circuit is only
connected to the circuit and/or circuit board and nothing else. If the
isolation ground circuit shorts to a conductive housing, then there is a
ground detection circuit that opens up a contactor or a shunt type
commercial circuit breaker.

Yes, I've taken out that LED light already, and it has a separate
set of
wires.

J1772 wiring involved anything with the lighting setup.
