Up for sale is the extremely rare NOS Intermittent Wiper switch. I have 2, they are $275 each. This switch is needed in conjunction with the Intermittent Wiper Governor to operate properly. (I have listed on another auction) This switch fits 1969-1970 Mustang, Boss, Shelby, Mach 1, and Cougars. Simple Installation, replaces your current 2 speed switch, then plugs into the Governor mounted on the firewall. Why not separate your car from all the others, by upgrading to an Ultra rare Factory Intermittent Wiper system. six one seven 799-5675
