Eagle Eyes Projection light

I just purchased the Eagle Eyes HD414-B0WHW they did not come with a wiring diagram looking for some assistence. It came with a wiring harness it has two (2) male plugs and one (1) female. I would assume the the two (2) males plug into the projection lights but what about the female. I called Eagle Eyes they said they do not have a diagram. Any help would be greatly appreicated. Thanks in advance for the help......
