  1. Dave Rongey says:

    The power source wiring to a typical hood exhaust fan enter a junction box where there are black, white and ground or a ground screw terminal. So with that connection its color to color. From what you are describing you have taken apart the wiring that most likely involves the switch controls for the exhaust fan and the light, so you will need to identify the wiring to the switch for the light and the switch for the fan in order to make the correct connections for the fan and light. Your limited description of the unit and what you have taken apart does not provide enough information.
