I have a new Panasonic Fan for the bath. Vent up through roof. Outside the bath a have a switch to turn the light on. Inside the bath I have a GFI near the sink (switch is almost directly across from outlet). The fan has 3 wires. 1. Fan
3. Night Light (don't think I will use)
I have access from attic. I have two blacks/two whites/ground and a red that was capped off and just sitting capped when I took off the existing light. Those all fed into the old light.
