looking up under the dash of my 83 300SD, i foud two stray wires. let me explain the one i found a "home" for first. It is a green wire, with a circular black plug with on prong in the middle of it. It connects to the back of the instrument cluster. I don't notice anything new working since i plugged it in so what does this thing do?? second wire is a black wire, also up under the dash, that appears to come from around the area of the lock tumbler. It has two prongs inside of it, and the plug itself is flat on one side, and curved on the other. Almost like a portable boom-box power cord type deal. Thanks for your help,
Ryan
