Furnace inducer motor wiring connection

I'm installing a new inducer motor fan assembly in a 20-yo thermopride gas furnace. The motor has 2 wires to connect. One of the black wires from the motor is connected to a yellow wire in an electrical box, the other is connected to three white wires in the same box.

One of the two black wires on the new motor has a red connecter on the end, the other is not marked. Does the wire with the red fitting go with the single yellow wire, or the 3 white wires?

I had hoped to open the electrical box and find fittings like the ones that are on the new motor, not a bunch of wires connected with wire nuts. Perhaps it doesn’t matter. Maybe the motor will run backward if I guess wrong, which would be detectable and easily changed.

I would put the lead with the red on it to the yellow wire, and the other to the white wires.

It's a 120 volt ac motor. Switching the wires probably wouldn't make any difference but I would agree with hvactechfw.
