Two questions as I'm working on a similar setup.
1. How did you mount the sensors?
They are too small and slide through the holes on my setup. Was going to just wrap the sensors with electrical tape until they won't fall through the holes. The included rubber grommets are entirely the wrong shape/size.
2. How did you wire that grille to your lights? I have the same and am trying to avoid cutting into the factory harness.
Actually last question, looks like you wanted to sell your bumpers, how come?
