I have three driveway post lites 110 volt, wired direct on ALL the time. I would like to install a motion sensor? I need a wiring diagram, or a good explination on how to install it . Tahnk

First question would be, where do you want this motion sensor to be located?

1 at each end?

At the end of the circuit , the furthest from the main power supply.

At the very furtherest from source of power

Then you will need a switchleg back to each light.
Power to motion comes from switch, then the motion out goes to each light(usually a red wire.
I would consider a motion at the other end as well. So when you leave, you will have lights also.
Just connect both motions black that comes from your switch for power, and the red of both motions connect to lights switchleg.
Either one detects motion, lights kick on, will turn off when last motion activated times out.
