Hi new member with 2020 GT R. Didn’t see a good fuse chart / diagram posted. The one uploaded by poster previously in this forum is hard to read. Thought I’d share this one out of the work manual which has a more standard layout and easier to use. (If you look at the files, you’ll understand)

Do you also have details on where the "Front Prefuse Box" is located and how to access it?

It's part of and underneath the B+ jumper battery terminal in the engine compartment, just ahead of the battery itself.
