Yes actually I do know. When I got my smart, it came from a dealer who bought a bunch from a rental company. The dealership said that the software was not compatible with the models the rental company bought. So the dealership got a deal and so did I buying a 2015 (2014 451) with only 20 miles. The dealership had a bunch and I noticed this cable on one of them. I do believe that the original rental company attempted to install their hardware and left the wiring behind.Hey all,
Was taking a closer look at my car (451) 2015 today and I found a factory harness lead with a flat black plug attached sitting on left side of dash between door and top of dash near windshield.
Any idea what it might go to or be used for?
