I can provide a wiring diagram if that will help. I need to know about how old this unit is

11/20/1997 I have a diagram that came with the furnace plus one that was on the blower cover, but their are 3 more wires than the diagram shows. (different speeds) I may be asking something that can not be found. Gene

Do you have the capacitor connections? The additional fan speed wires can be wire nutted off.
