Just so.

Only one of the "cross-over" wires winds up being unused on a LHD car, which
is the green/red wire.  You don't need to have that one.  The green/white
and green/brown wires are used, so something is not going to work properly
if you leave those out.

The black wire is a ground wire, not shown on the diagram.  But I strongly
suggest using it (it goes to a ground clip on the body, behind the horns on
each side) as the US-spec headlight bulbs are not grounded to the buckets,
and the buckets are not securely grounded to the body.  IOW, your headlights
won't work right without it.

I've attached a copy of a factory wiring diagram, modified (sort of) for
LHD.
