i've found a mystery disconnected cable while fixing a leaking wind screen wash bottle its about 18 inches long and branches from the cable that connects to the bottom of the bottle and has a yellow plug , ive looked everywhere but can't see a connection point and as the car has never been worked on in this arrear im wondering if its a sparefor retro fitting fog lights in the bumper as this model doesn't have them, there are even grovesin the bottle to accept it
