Usually the dealer drills the holes as part of their prep before delivering the vehicle to you. I've specifically requested that they not do this.... You'll probably have to drill into the bumper or find some aftermarket way to do it... Personally I just wouldn't add it. I've never had a problem without one.
Yeah I'm going to have to get it done or do it (can't get the dealer to do it as I ordered the truck from across country and they shipped it to me so I'll pay to have it done here I guess). Probably have my local car audio shop just do it for me as I'll be there right after the truck comes in my buddy works there and wants to see it.
