2015 RZR 900 trail, wire left unplugged??

Hello:
Just doing maintenance on my 2015 RZR 900 trail with EPS and rear diff unlock feature.
I noticed a 2 wire plug left unplugged from factory, I need help to figure out what it is for.
It is located on the drivers rear diff. just above left rear axle, it has a mate to plug into but it was left unplugged, the 2 wire female mate plug goes to a screw on can just above rear diff. axle , it almost looks like a oil filter with 2 wires coming out of it.
I was thinking it might be for the rear diff. unlock or turf mode feature this machine has on it.
What do you think???

Thanks
