First is the capacitor built in or on the motor? Usually they connect with 2 brown wires. As far as Mains power the White is neutral in the US, the Blk(hi), Blue(med), and Red(lo) is the common and are normally used for multi speeds. Some have additional wires that set the Rotation, GE motors have an additional 4 wires that are Brn, Yel, Org, Purp. These connect Brn to org, and Yel to Purp for CCW and switch the yel and org for CW. Now your motor may have these internally? or jumpers inside the cover plate?
Hope this helps in some way.
