The 7-pin hitch connector box is in an awkward location for hitch-mounted bike racks. I have never towed anything that requires the connector, nor do I have any plans to do so soon, so I finally got around to removing it.
The red clip slides to the left, then the plug comes apart.
Removed 2 reverse torx screws with a ratchet. Some people have a welded box here, but mine is not, fortunately.
