knocking noises in the backend:

I went nuts trying to pinpoint a "plastic-on-plastic" sounding knock when I went over bumps. Turned out to be the wire inside the back cladding that goes to the red light on each side. I secured the excess slack with a ziptie and the knocking sound went away. Also, I put some shop rags in the compartment with the tire wrench because it'll make some noise when going over bumps as well.
