on a 99 E320 I spilt a drink from the drink holder onto the shifter and power window switches. i pulled it apart to clean up the mess and found a loose wire thet is black with brown tracer or brown with black tracer. i onle see two plug ins and I see no wires off one has 6 wires into it the other has three. the loos wire i have found hasa metal push pin on the end like one that could have come out of a plastic housing? Thatnks for any help.
