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 connector) that looked like it should have been connected to the switch but wasn't. I was afraid to connect it and cause a short. There are only three wires connected to it and there all connected on one side of the switch. (Not sure if this is correct or not). . 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 but it was just odd that it was right at the switch and due to length it couldnt have reached any others.
