I know this thread is plenty old, but I'm working with the same fuse box illustrated above, and I'm trying to get my dome light working. My box was missing the fuse in the #7 spot. The diagram says it needs a 15 amp fuse, and thats what I tried to put in, but it doesn't fit. It's about a 1/16 of an inch too long and I can't get it in there for the life of me. I suspect thats why the PO didn't have one in there also. Has anyone else run into this problem?
