wire motion sensor on extension cord

I had a great idea for Halloween. In order to do what I want I wanted to wire a motion sensor from an exterior light to the extension cord. The idea is that the sensor will allow intermintant power to what ever is attached to the cord.
I have a cord that already got split at one point.
I started with 2 pieces of extension cord and the motion sensor.
Out of the sensor are 3 wires; red, black and white. I wire all 3 whites together. I wired the black from the sensor to the black on the extension cord piece that plugged into the wall. The red I attached to the black on the female side.
The ground was not split.
after writing the above, I swapped the sensor red/black connections. Now I have power through the cord,but it is constant, not intermittent like I want. In the light the sensor was wired the following way:
Black to black power in, whiter to light whites, red to light blacks.
So, how do I get it to be intermittent?

Most motion sensors also have a light sensor in them so that don't operate when they see light.
Could that be your problem ? Your wiring sounds ok.
