The original fit OK but not as tight as I'd like. I added small tabs to lock into the balance plug clipping mechanism. They fit so well you need to be careful when removing. May need to push balance plug through the hold while pulling on plug from other side. Be sure not to tug on wires too much.

I also added a bump to add more tension. May be trimmed if too tight depending on your specific plug.
