Replacing a 115V 3spd blower motor for air handler in older gas furnace. New motor wiring diagram explains thuroughly exept where red wire of 3 conductor R,WH, BLK coming from control panel. Rotation wiring correct from box. Got 2 browns to capacitor, white to white, and black to black-high speed.

One will be for heat and the other for cool. Most guys use high for cool but it really depends on AC size and furnace temp rise.
