assembly. When the wiper is at MIST, the terminal 2 and terminal 11 should be conducted. When 
at OFF, terminal 2 and terminal 10 should be conducted; when at INT, terminal 2 and terminal 10 
should be conducted as well as terminal 2 and terminal 11; when at LO, terminal 2 and terminal 11 
should be conducted; when at HI, terminal 11 and terminal 1 should be conducted.
