Hello! My name is Mark Neibuhr. I recently inherited my late uncles 1989 25' ecella airstream. It is in "mint" condition! He was very meticulous in maintaining it. Needless to say I am very excited about using it! However their is one small problem. The 12 volt DC furnace doesn't work. Their is a
"cut out" near the floor in the cabinet below the stove right as you step into the trailer. I think this was for a "fan switch"? Whatever is supposed to go there is missing. There is also a "red" wire and a "white" wire that have been capped of with a wire nut and elec tape. I would sure appreciate any
help as to how to get this working properly.

Thanks
Mark N.
