Does anyone know if a 1972 3 speed wiper motor wires will work on a 1970?

I am well aware of the plug and play interchange between wiper motors considering body styles, years, and wiper styles... But, I am unable to find a reasonably priced PN 2983116 wiper motor that is in good shape...

The reason I need one is someone cut the harness off of mine and left the motor in place... The 3 speed wires are not pluggable and are soldered/hardwired into it...

I have read that there is a difference in the 72 motor vs 70 on a Dart, mechanically, but what if I cut the wires off a 72 and spliced them onto my current system?

Are they the same electronically????
This my 70 with cut wires...

Then the next are the 72 set up...
