Windshield wiper switch-AARGH!

Hey hemi,sent you a pm with address,thanks for the help. Red,I know it sounds bizarre but this is the way I found it and the wiring diagram confirms this madness. The only reason I can come up with was that it was convenient for the builders and saved some dash space? I've been finding that this particular car seems to be sort of a potluck of parts,maybe they were just getting rid of leftover parts. I dunno.
