Need help identifying a component on 1998 HDJ100 (2 Viewers)

[dstar]

I am looking for assistance in identifying a component. While under my new to me HDJ100L changing the CDL switch, I found this on the left side past the transfer case toward the rear. You can see the screw that has been made into an electrical terminal. Looking for a steer on what component it is so I can further research and formulate a plan. Thank you.
