Wiring a Dusk to Dawn Photocell Sensor

I bought a photocell sensor on eBay after learning Lowes, Home Depot, and Walmart were either out of stock on them or did not carry them.  No problem, I thought, 3 wires and it should come with instructions.  It arrived, but with no instructions except on the little plastic part (see second photo).  I am NOT an electrician, but usually can handle easy projects.  If it had 2 wires, it should be easy, but with 3......that's a problem.  I went online to instructables, Youtube, and a few other sites.  Although I could not find anything showing what I needed, I did gather enough to attempt it.  Here is my wiring diagram ( third photo) and instructions:

CAUTION: BLACK WIRE IS 120 VOLTS, SO TURN OFF SWITCH OR CIRCUIT BREAKER.

Connect sensor's black wire to black wire coming from house.
Connect red sensor wire to light's black wire .
Connect all 3 white wires (from house, from sensor and from light) together.

Now wasn't that easy. :-)

These are very reliable photo sensors or photoelectric switch as it says on the back. I used these on my instructable. As a matter of fact I found your instructable useful in helping me make mine, Thanks. I selected "I made it" not because I made it but because I used you as a refrence.

You are welcome, Chanio. This is really a good sensor. I have bought two more since then and it only took minutes to install them.

Cool.

Thanks Magicninjalord & Chanio. The photocell worked flawlessly last night and turned light off this morning. :-)
