Mystery solved. It made sense that it would be the e brake cable, but it didn’t make sense that if Ford installed it, it would be so tight as to interfere with the step well cover (which it does). Well, never underestimate Thor’s ability to screw something up! It is indeed the Ford OEM e brake cable. But in the undercarriage, Thor zip tied the auto leveler hydraulic lines to the brake line, and they must have pulled the brake line through the hole during installation. Oh Thor. Thor, Thor, Thor......
