Empty FuseBox Terminal

The dark Blues are rear window defogger and tach. If your car doesn't have those, then no obvious need for the jumper.

Not sure if the car has rear defrost but it does have a tach. I do have a black jumper (pretty sure it's black), it goes from the second terminal from the top left to the third on the bottom. It's the wire that has a bit of white paint on it.
