Kurt, that is not a "fuse" it's actually a static suppressor for the radio.
Unless you care about looks or want to get the car judged, I would eliminate it and just save it in case someone wants it in the future. Functionally, it can do a lot more harm than good if it goes bad. Also, the newer radios don't need it. B/T/W, it's not connected correctly in your photos
ps black wire is ground
