help wiring blower motor

My old motor is an a.o.smith F48D30B22, the new one is an a.o.smith DL1036. They both have yellow, black, blue, and red wires, but the old motor also has a white wire. I can't find a wiring diagram, what goes where? It looks like the white is neutral, should there be a neutral on the new motor?

Yes, you have to have a neutral wire, as that is needed to complete the circuit for anything with 120 AC current. (But not for 240 AC current)

Color wires may be for speed. Some motors give color wire speeds listed right on the motor itself. But in light of the fact no double brown wires for capacitor, I can't say for sure, unless you have an internal capacitor? I'd call up a motor shop and ask one of the guys.
