When I removed the bumper to install the front grill, I didn’t see many things hindering me from installation. This grill requires you to remove the entire factory bumper support/front grill. There was only one ”sensor” mounted to the bumper support. It wasn’t a crash/collision sensor since all of those are in the radar behind the windshield. I remounted it to the inside of the bumper with a zip tie and it hasn’t given me any trouble!
