I did my own, second one too.

The disc is actually the end of a missing shifter cable boot, if it's like it is in my photo. Not sure why it's not there. Thought it was an omission on my car but if others are missing it too, who knows.
On my JSW it's definitely present.
Sorry the photo sucks, taken with an iPhone as an afterthought.
