How do you wire a 3 way power switch and leg in the same box?

Since your incoming power and switch leg are in the same box we have to send power to the farthest switch ( switch #2 ), which we do with the white wire from the 12/3. This will energize the travelers, the black and red wires from the 12/3. We then attach the black wire from the fixture to the black screw on switch #1.
