i had a 3 speed blow motor to an AC fan coil unit. I disconnected the wiring and installed a new unit and forgot how the wiring goes, i no expert and dont want to burn anything out...

from my electrical panel to the blower motor, I have a wire that has 120v, another wire has 40v, and a 3rd wire with 0volts

on the motor i have a white thats labeled common, a black, red, blue are all labeled for different speeds....

i forgot how the other motor connected the 3 wires i mention above.... can anyone suggest ? thanks

can i connect white 0volt to common and 120v to high speed wire on motor? where would 40v wire go? thanks for any ideas
