Not sure where the outside temperature sensor was supposed to go originally.
In my coach, both wiring leads go to the bay. One of the temperature sensors appears to be buried behind the waste holding tank. In my case, that is the sensor that shows an error. The other sensor was taped up and hanging from the drain line on the driver's side near the dump valve. Since I find the temperature in the bay more important than the outside temperature, I have left the outside sensor hanging from the drain pipe. I have thought about contacting PMI who made the temperature gauge about a replacement but haven't gotten around to it yet.
