Hi,
If you are not getting power to the box under the hood, there could be an issue with the box itself.
I attached a pic of the under hood box and highlighted a fuse (Batt). It is one of the mega fuses. Make sure it is good and check it for power to and from. Also, inspect the other mega fuses as well.
Here is a link you may find helpful:

Let me know what you find or if you have other questions.
Take care,
Joe
