I'm glad you got yours working Jon. I tried every combination possible with mine even to the point of adding shunts across to the extra terminals in case both ins and both outs needed to be used. Then I read in Amazons reviews that a small but not insignificant percentage is defective. I was able to find a box that it fit. I think it was the same plastic waterproof box I used for the switch I have now.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
