The salesman said it is a trailer brake fuse. It might be, because my Harley hitch cover doesn't light up like it should.

Thanks!

Actually I believe the (electric) Trailer brakes will still work, I believe this is the "trailer" battery charging relay and fuse...

I appreciate the effort someone took to update and provide detail with documentation about specifics many of us may have not fully understood no matter the age of the post.

The dealer wouldn't sell me the fuse and relay unless I provided the part number. Very weird. Service couldn't help me either without first paying a diagnostic fee. How lame is that. So this thread saved me a diagnostic fee.
