I know what you mean, I just bought mine too. If you look real close at the front bumper you will see two tiny dimples where HOLES will be drilled to rivet the bracket on. The bracket should be in the back of the car under the floor. When you go back to the dealer to get your real plates put on, they will install it.
I am dreading that day. Take a few pictures from the front without the plate so you can remember how good it looked.
It TX it's illegal to run without the front plate and the cops are pretty rude about it.
