Hi 69novashotgun,

The wiper motor you need should have 3 terminals and a rectangular (not round) motor housing. The pump should have 2 terminals.

One of the 2-wire plugs goes to the washer pump. The other 2-wire plug along with the single-wire plug go to the motor.

On the 3 motor terminals, one is spaced farther away from the rest ... that one takes the single-wire plug. And the 2-wire plugs have at least one "index notch" that lines up with an "index tab" on the corresponding motor/pump terminal. If you get them mixed up, the index tab will keep an un-notched plug from going all the way on.
