1970 swinger wiper switch and speedo

hi. guys and gals looking for information. have a 1970 swinger but unfortunalely the speedo mileage counter is not working. the needle move. removed speedo #2927719
when I turn where cable goes in no gears move. does anybody have a picture of a working
unit so I can figure out what is missing to make the mileage counter numbers move.
hard to find any information on this.
also wiper switch needs to be changed but when I removed dash no proper connector.
only 3 push on wire leads added to three wires. believe to be a 2 speed wiper motor.
does anybody know which switch number and how to wire without the proper clip
