Free hanging Plug in Motor access area?

I was recently checking the Drive Motor area at the rear of the Bullet to see if I needed to do any cleaning. It was “clean as a whistle”, but I also noticed a Plug just hanging freely. My Bullet is working just fine, so I expect this is for some future addition or maybe for testing? Anyone know the purpose of this Plug?

It has been mentioned somewhere before but it’s normal - probably something to do with original production line testing

Soooo, maybe this is where we will connect the optional Bullet “Afterburner” (one day)… :rocket: :sunglasses:
