The problem on a 2007 F150 from Texas(in OHIO now), and what it looked like after the fix. This doesn't look like somebody missed something reassembling. Looks like it's just Ford oversight.
Got towed in, I replace a fuse, seemed fine until we looked harder.
Had a "bank 2 lean" code that went away on it's own after this fix too.
