Never mind... I found it. I searched for it before but didn't think I had as much access as I do.
It is located above the propane tank on the passenger side. All of the connections and sensors are easily accessible, and it looks like the tank just slides out and then back in and has some brackets keeping it from moving around too much.
Feel kind of stupid.. but at least it looks like it shouldn't be a difficult job... which is a real change since everything else seems like you need to be born in there to actually work on it...
