I suspect this may be to do with the 2016-2018 GV250 harness being updated to use a special box that has a lot of fuses for different parts of the bike, due to the suspicion of me seeing a lot of orange / red wires going to it.
Generally red and orange signify live wires on hyosung bikes but Hyosung “may change” later on.
You should checkout also the 250cc EFi service manual which has a wiring diagram (Delphi GT & GV behave the same but GV just has extra sensor or 2. ) , if you don’t see the manual on this forum , there is also the alternative source called ManualsLIB which should have a 2016-2018 delphi manual.
I know it is Delphi as i can see the black and grey connectors for the ECU.
