If your motor has the number XXXX.dat, you can create a XXXXc01.dat assembly
consisting of the motor plus LSYNTHed cable plus plug.
Such a thing for example would be useful to show in a set inventory.
So the arrangement of the cable should be done "visually pleasing".
My suggestion would be to only do this if the cable is firmly attached to the motor
and cannot be removed by the user.
If the latter is the case, the 2 clearly are 2 separate parts,
and should also be shown that way in a set's inventory.
