Thanks Denny!! A picture is worth a thousand words,in this case ten thousand.I see what my problem is now. On the original 6volt motor the wires are fully inside the cab when the fresh air is mounted.On the replacement 12volt which is longer the wires are outside in the engine bay past the round motor seal.Sometimes I wonder if these guys that make repops and sell them as direct replacements have ever seen the original parts!Until now I had never seen an original fan switch! Simple,solid,and the perfect look for the truck which is why they aren't reproduced, makes mine look like a piece of junk.I'll be searching for one of those new old stock. Jimmy
