Now, the part number for the fuse box in the photo is 12110746.
The datasheet is available online:

If you look at the bottom right corner, it tells you that the terminals in the fuse box are Metri-Pack 280 tangless: "ASM FUSBLK PRTD
MP 280 TNGLS".
Now, having replaced fuse block terminals in my own, I think the actual terminals are Metri-Pack 280 tangless bus bar terminals. They look like this:
Metri-Pack 280 female, bus bar, tangless, unsealed terminals:

Metri-Pack 280 female, bus bar, tangless, sealed terminals:

Whether you need unsealed or sealed, you'll have to take a look at the fuse box and see if the terminals have seals. I think they do since they are in the engine bay, and most all terminals in the engine bay will be sealed terminals. (Although there are some exceptions, such as the 7.4L alternator connector which uses unsealed terminals because the connector itself is sealed.)
Now, which Metri-Pack 280 bus bar female sealed terminal you need will depend on the gauge of the wire you plan to use. Any idea?
