How can I install an outdoor light sensor? I have 3 wires white, red and black on the sensor, but there is only 2 color wires on the light, black and white and also a metal wire (ground).
Now what you can do in order to make this work if your installing the photocell at the light itself is either leave the light switch on so that you have constant power to the photocell, or bypass the switch and leave power on all the time at the light in order to power the photocell. See diagram for how to wire this unit. Hope this helps, if you need anything further - just let me know. Have a great night.
thanks, got it
