Windshield Washer Motor Install Help

I do have the Wiper Switch that does allow me to push for washer fluid, the car doesn't have a foot pump. Its a 1972 Plymouth duster. I am not sure if any of the wiring is installed but I am hoping that someone just cut the plug off or never hooked up the wire. But if the wire is to come through the bulk head I can follow it and know if the wire is there but just not connected.
