Great one Z!!! Totally true!
Well, I'm at a loss. Mine was a pain in the rear because you have to lay in the trunk and remove/peel back the side panel that runs the length of the trunk to access. Once I accessed the module, I had to unbolt it in order to see it at all since it's between the seat back and frame of the trunk.
Once unbolted and out in plain sight, it does not have any numbers on it. I even took pictures of each side and then blew them up on my computer. Nothing. At this point, I'm clueless.
