The 60 amp is usually a smaller gauge hot wire than your pic with just a ring terminal with no red cap. The wires on a standard 60 amp go under a metal plate at the back. On the Niehoff there is an external stud and that is why it has that cap. Also the Niehoffs use the extra external ground...
I think you have the 100 or 200 amp set up not the 60 amp. Those 2 wires look they go the "upgraded" Niehoff alt.
Did the 60 amp mount up ok? I do not know if they are backwards compatible?
