    Default motion sensor wiring

    i am installing a motion sensor light over the back door where
    there is no previous fixture. how much drywall do i have to remove
    inside to connect to double switch inside by the door, and can i
    disconnect one of the switches that we dont use and connect the
    motion sensor light to this switch. thanks to anyone who can
    help. tom t.

    If you go to the side of the door, you shouldn't have to remove any drywall at all, just cut your new light fixture hole for a 'cut in' style box and pull the switches out of the interior box, leaving them attached to their wiring.

    This should give you enough space to snake a new wire from the fixture to the switch box, you may need a helper, and it might be easier to back fish a smaller wire from the switch box to the fixture opening.

    What is being controlled by the existing switches, and how many wires are attached to the switches and bundled in the box?

    ALWAYS turn off the electricity before opening or working on circuitry.
