Today I was installing some upgraded electronics and while under the dash I noticed something with he wiring on my jackplate switch. There was a large black wire (female connection) that looked like it should have been connected to the switch but wasn't. It was just hanging near it like it had came undone. I was afraid to connect it and cause a short. The plate though does run very slowly but I rarely move it. Ill try and get a pic if I can to help.

I wouldnt think the plate would even work if this was the ground wire??
