Hi, I had a little grille damage so I ordered a replacement (below). I do not necessarily need to connect the lights. I wanted the all black look. However, if I do connect the lights, is it as simple as extending the wiring on each side, to the running light wire at the back of each of the headlights? Maybe just wire all four to one side? It does not appear as if there are instructions on the electrical portion of the grille installation. Thanks
