Took the trailer harness out of the glove box and noticed something rattling inside of it,  here is what I found.

Ones screw looks like it was never installed and the other was an extra.

[2015 Z Force 800 53/Trail EPS]

Mine rattles too...Guess I know why now.

Easy way to short out and blow a fuse or damage something .

Mines in a ziplock bag sitting on my bench....haven't heard a peep out of it.
Actually, the dealer had to take it apart upon delivery as it wouldn't line up with the plug on the Z to plug it in!
