Foglights? Some cars come with the extra lead even if there are no fog ights installed on the car.

You'll need a US wiring diagram, those wire codes don't seem to relate to anything here that fits, one of those color combos is the sunroof here.

Silly question where did the spare connector come from? did you get a new wiring harness?
