The presence of the red wire in a light switch situation usually involves a 3 way switch. The light itself would only have the black and white running to it but the switches have the extra wire between them for the traveler.
See the Related Link shown below for a diagram, or just Google "3 way switch diagram".
What else can I help you with?
I see only a red and a green wire coming out from ceiling box. What are they and how do you connect them to a ceiling light?
Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
How do you wire a light switch with only black and red wires?
The black wire is typically the hot wire that carries the electrical current, while the red wire is often used as a traveler wire. Connect the black wire to one terminal of the light switch and the red wire to the other terminal. Make sure to turn off the power before wiring the switch to avoid electrical shock.
How do you connect red white black and green form USB to a two wire cable having red lack?
You can connect the red wire from the USB cable to the red wire of the two-wire cable. The black wire from the USB cable can be connected to the black wire of the two-wire cable. As for the white and green wires from the USB cable, since the two-wire cable only has a red and black wire, you can leave the white and green wires unconnected as they are not needed in this case. Just make sure to insulate the unused wires properly to avoid any short circuits.
How do you install a doorbell with four wires both having black and red wires?
It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.
What does the red wire do in the ceiling?
You connect it with the same hot wire as the black wire in the fan. It is intended to be tied to a different switch. One for the fan, and one for the light kit.

How do you wire an RJ11 telephone jack?
To connect an RJ11 telephone jack, first, strip the telephone line providing the dial tone. Then, strip those wires to show the copper. Then, loosen the screws on the jack. Connect the red wire to the red screw, and tighten the screw. Connect the green wire to the green screw, and tighten the screw. Connect the black wire to the black screw, and tighten the screw. Connect the yellow wire to the yellow screw, and tighten the screw. If the wiring does not match the colors of the jack, then follow these steps: First, connect the blue wire to the red screw, and tighten the screw. Then, connect the blue/white wire to the green screw, and tighten the screw. Then, connect the orange/white wire to the black screw, and tighten the screw. Then, connect the orange wire to the yellow screw, and tighten the screw. Then, screw the jack onto the wall with the appropriate screws. Connect a working telephone to the jack, and check for a dial tone. If you hear a dial tone, then you have successfully connected all of the wires to the jack. If you do not hear a dial tone, check to make sure that all of the wires are securely on the screws, and that none of the copper has come off of the wire.
How do you wire a sub in a Saturn sc?

Where do you connect the fuse cable wire from a car stereo you have a Red wire that is the live a black wire that is earth and a yellow wire that is for fuse where do you connect the yellow wire too?
Red goes to a switched live i.e one that is only live when the ignition is switched on. Yellow goes to a permanent live i.e one that is always live whether the ignition is n or not, like the cigarette lighter, and maintains the station configuration memory. However, a modern car should have a pre-wired Din connector and a local motor factor will have the corresponding universal adaptor for your radio; connect colour ro colour (inc speaker wires) and plug it in !

How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.
How do you hook up an overhead light in the kitchen to a two way switch?
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.
How do you wire a Floodlight with motion sensor that has one black one red one white and one bare wire but also one black and one white which are each wrapped in a fiber material?
The best advice I can give you is to reference the wiring diagram that came with the flood light fixture. There's no sure way for me to know what the wires are, so if I gave you an answer, it may or may not be correct. Typically, though, the wires are as follows: Green or bare - ground White - neutral Black - hot Red - switched hot The 'fiber' coated wires are probably high-temperature fixture wires. These go to the actual lamp. The others operate the motion sensor. You'd have to connect your bare to the other ground wire(s) in the junction box, or the box itself if it is metal and there are no ground wires. Connect both your white wires (normal and fiber coated) to the white wire in the junction box with a wire nut. Next, connect the red motion sensor wire to the black fiber coated wire with a wire nut. Last, connect the black motion sensor (non-fiber) wire to the black (guessing?) wire in your junction box. Remember that you must leave the switch controlling the light in the 'on' position to allow the motion sensor to operate properly.
Where does the blue wire connect from a sportster speedometer?

Where does the negative wire from the battery connect to on the alternator?
There isn't a black connection on the alternator? That would be the correct side. If not, you could almost connect it to the bolt that holds down the alternator to the frame of the car. Check with someone else to be sure, but the negative side or connection is the common or ground wire. Just avoid hooking it to red.
