I'm missing some fuses that aren't on the dash diagram. Panel says to contact dealership for further electrical parts not addressed on the panel. Anybody have a diagram w/ all the parts? I need to change the fuse for my passenger side back door and alarm system.

They should be under the hood in the relay box .

I'm not entirely sure what the instructions you are reading mean by that exactly. But I do think what you are seeing on the fuse panel are some fuse terminals that by design are deliberately empty. They are reserved for any fuses you may need for any after-market electrical changes, modifications or other additions to the car.
I don't have a complete fuse diagram that would include the location of the fuse for your alarm system. I think they are often left unlabeled for security reasons; in the event of a break in to the vehicle that could allow access to the panel and disable the system by pulling the fuse. In the case you never get the diagram, you could probably use the existing factory diagram you do have and by process of elimination, see if you have fuses installed in the panel that are NOT on that diagram. Pull that fuse making note of it's location, check it to see if it is burned out. If it is, you can "borrow" a fuse of the same rating from elsewhere on the panel and put it into the spot of the burned fuse and see if the alarm operates.
