Yep, been there, done that, got the t-shirt, as far as PO Syndrome.
At least this time it's only a fuse you have to replace. On mine, I had to cut out and splice in new headlight bulb connectors - because the PO had put 100 watt Euro bulbs in the headlights and literally MELTED the connectors.
While you're at the junkyard, best grab a new cover for the GP relay as well - the PO has cut away part of it so he could jury-rig in that spade fuse.
