PLEASE HELP, Rattles ugh !!!

[jcm11]

I had a rattle in the right rear some where as well. Sounded like something hitting metal. Did it all the time coming to a stop and acceleration off the line. No noise at highway speed. Around town drove me nuts. After taking out all the right rear trim and riding around in the back it turned out a harness that plugs into the passenger side rear seat belt behind the C pillar trim was rubbing on the long bolts from the right rear door latch. Taped the harness, wrapped it in auto wire harness foam where it passes through the opening and them put sound deadening material over the harness. No more noise.
