Yes, you can re-use the single speed wiper motor wiring for the 2 speed motor with washer. However, you will have to add a couple more wires.
The single speed motor would have only had 2 wires ... a +12V feed wire and a switched ground wire. That switched ground wire can be re-used for one of the wiper's speeds. But you'll need to add another switched ground for the 2nd speed. And a 3rd switched ground for the washer pump.

Here is a photo of a 2 speed wiper motor with washer.
This one is a slightly newer motor so it might look a little different than yours but the terminal layout should be the same. I have marked the terminals in the photo according to the diagrams in the 70's GM shop manuals.
Your +12V feed wire should run to the #2 "power" terminal. Then feed power to the washer solenoid by running a short jumper wire from the #4 "power" terminal over to one of the "washer" terminals.
The motor's #1 "high" terminal should be wired directly to the corresponding "high" terminal on the dash switch.
Similarly, the motor's #3 "low" terminal should be wired directly to the corresponding "low" terminal on the switch.
And the remaining "washer" terminal should be wired directly to the "washer" terminal on the dash switch.
