There isn't much. You can easily pop off the black plastic to take a look yourself, just
1. unbolt your wiper arms.
2. pop the hood
3. remove the rubber seal at the back of the engine bay that the hood panel seals against when it is closed.
4. The black plastic trim is held on by snap pins, a couple large ones that you can see from the engine bay and some that you will feel when you start trying to lift up the plastic trim.
Richard Krenn has a photo of the underside of the plastic trim where you can see the pins so you get the idea.
