Thanks for the quick responses guys. You gave me confidence that it's not factory so I decided to dig it out before closing everything up again. Here's the pics of the sensor and the hole it was "installed" in.

Net says it's an external temp sensor. ATI is still in business as a subsidiary of somebody else, but the part number is not recognized. Based on current products, it looks like it just went to some display / processor in the coach. In all fairness, only the tip of the sensor went through the hole and the wiring upstream of the photo is in a split loom conduit that appears factory, hence my confusion. Because I'm not sure what else it may be connected to, I'm leaving it as-is for now. IMHO, a strange location to install a temp sensor.

Another mystery solved by the WOG!
