I am trying to have my bathroom light/fan operate separately, with one switch operating the light and the other operating the fan. The power coming from the switches is 6 wires (2 black, 2 white,1 red and ground). The wire coming from the light/fan is 4 wire (black, white, red, and ground). I have 2 switches. How do I run the wires to the switches so that the light works from one switch and the fan works from the other?
