I have a 99 F-250 with 7.3. I'm having GEM and interior fuse box issues. I have already pulled both. I have opened the GEM module and looked over all of the connections. Everything looks ok. I want to open the fuse box up, but I can not seem to figure out how to. It appears to be the studs/harness threads are keeping me from opening it. Has anyone ever opened one up before?
