Joe-K I have a 2004 Meridian and have wondered the same thing. There is so much stuff under the front of these coaches, what shape or form will the sensor look like and how many wires run to it?

On mine, it's at the very bottom of the front cap. It's attached to the bottom lip of the cap about a foot from the center toward the driver's side. Two wires connect to it.
The fact that it's under the front cap probably explains why the outside temp goes up a few degrees when I'm stuck in slow traffic--the hot air probably collects under there and gives a false reading.
