Hey all,

I was doing some work behind the instrument cluster on my 83 300sd today, and I noticed these three black wires that go to one metal plug. They were just hanging out, but I figure they need a home somewhere. I can't find anything on the back of the instrument cluster they go to. I pulled off the lower kick panel to have a look underneath, and I can see the three wires come from on top the vent area. I thought they might be a part of the fiber optic lighting, but they do not light up when I reconnect the dimmer and turn the lights on. Any thoughts?
