Was replacing the battery and noticed a wire that was unclipped. It was at the front of the engine bay. One point led from a pipe next to the alternator and the other end went under one of the radiator hoses and of to the left of the car under the engine. Black wire with electrical style oval connection and clip. Behind the clip was what looked like a plastic bolt. Sorry not got a picture, just curious as to what it may have been. It was the smallest wire in the area.
