Alex,

I haven't got around to replacing my sensor yet. The wiring for the new sensor is quite long, so I plan to keep the old sensor in the side of the bumper, and wire in the new one behind the front license plate. I think the procedure for installing the sensor is in the service CD's. It is routed behind the bumper (bumper removal is not necessary) and driver's side headlight, and up along the top of the wheel well into the fusebox.
