I'm trying yo wire an outside motion detector that has 2 flood lights (each has a blach & white wire coming out the back} and a motion detector that has 2 white, 1 black and 1 RED coming out the back, I've tried several wiring connections but can't get the motion detector to turn the lights on. Can anyone tell me how to wire this thing. (There is no ground wire}. Thanks! Mark

I am installing a bathroom light /exhaust fan and there are three wires in the fan blue black and white.
I have only two wires comig from the switch black and white.
I have connected these with the blue unconnected but the light or fan does not work .
Do I need to connect the blue wire to some thing? or run another wire back to the switch and connect that
I have an on off switch at the moment but want to wire it for a swicth for the light and a switch for the fan in the same switch unit.

dnrunin,
First of all I don't know how your msg got mixed up here with the other but... Here's some info:
The black and white coming from your switch is the hot and neutral from the switch. The hot (black) is the wire that is actually switched, the white is not (white is never switched).
The white coming from the fan will go to the white from the switch. The blue and black from the fan will go to the black from the switch. This is the only way to wire it for now. So connect the blue and the two blacks all together with one wire nut. This is similar to (exactly actually) how you wire a ceiling fan/light combo. By the way, when you said you wired the black to black and white to white with blue unconnected, either the fan or light should have worked. So wire as I stated and check later if the fan and light work. If not, make sure the bulb is good and make sure the fan is plugged in. Most fan housings have a single outlet for the fan's power. This makes it easier to change out the fan motor later. If you want separate switches for the fan and light, you will need to run new cable through your walls from the switch to the fan assy. This cable will need to be the same gauge as what is there (for a bath, probably 12ga). I suggest if you want to rewire the fan, post a question later for the wiring involved.
Good Luck,
Brian
