Looks cool and fits well in the space for it. Did the kit have specs on how many watts these lights run at? It'd be interesting to know how many amps the aux connector on the Zeon can supply.
As for your connector, it seems the harness manufacturer did put the right contacts on the cables but shoved the wrong connector housing over it. I took a quick snapshot of this connector on my mower, without protective cap it looks like:
and this is how the aux connector came off factory with a plugged mating connector to keep the contacts protected from the elements:
It looks like the aux connector is powered by a separate DC-DC converter tucked away between electronics and battery compartment.
Good luck with the light kit, the days are starting to get shorter, I could have used one this week on my mower.
