You would need to look at the wiring diagram that came with the unit. Usually the wiring diagram is glued to one of the panels on the air conditioner. Hope you can read it. Rule of thumb on wiring the capacitor is: Herm on capacitor goes to the start winding on the compressor, Fan on capacitor goes to brown fan wire that goes to the fan, and Com on the capacitor comes off one leg of the contactor to provide power to the capacitor. There are usually more than one wire connected to the Com terminal. The Com terminal is used so other components of the air conditioner can steal power off the Com connection.
