@bracconiere I'll try to help you but no warranty expressed or implied. Lets start out and take the wires that cane off the motor in the first place and kinda place them by the motor. With the age of the unit, the wires might have a "memory" of their layout.
There should be a black, purple, brown/yellow, pink, and red wire.
The black & purple wires are one side of line the just go to and from the motor ("motor switch") on the wire diag and should not be needed for your use. They are 1 side of the line (L2) used only for the heat coils. They would go to "M1" and "M2" on the motor. (prevents power to the heat coils if the motor is not spinning) My guess would be the bottom two motor terminals.
The brown/yellow comes thru the door switch to the motor and is LN, or neutral. I should go to "M4" on the motor. I can't see any #'s on the motor terminals but my guess is the terminal that the orange wire on the motor is M4 because I'm also guessing the little thing with the orange & red is the motor thermal overload.
The red & pink wires may be piggy backed and belong on "M5", these are the 120v power or "L1". Thinking it would be connected to where the blue motor wire is.
At bare minimum your 120v legs should be on M4 & M5.
Hope this makes some sense and gets you a little closer.
Cheers and good luck,
