When using the correct size wire, there are several possible configurations of power connection, lighting outlet, and the two 3-way switches. Power can come from the panel to one switch or the other, or to the light, whichever is convenient. The light can be physically positioned between the switches or at the end of the two-switch series.
Each configuration requires different handling of the hot, switched travelers, and neutral wires. In every case, there are runs that require three parallel conductors, whether for neutral, hot or travelers, not including any grounding wires. A 3-wire cable is highly recommended for this application.
If there are more than two switch locations, a 4-way switch goes between the 3-way switches to crossover the two travelers. Two 3-conductor cables are used for this portion, including a bypass connection for the un-switched hot. Asking this question shows you are probably not quite ready to take on this particular task.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Yes. Instead of sending the hot wire straight from one of the three way switches to the light, put a dimmer switch on the hot wire to control the light.
Use two three way switches. Hot feed comes to one switch. Wire to light goes from other switch. Two travelers (same size wire as other wires) are needed between the two switches.
with 2 3-way switches you need 12/2 to the light and 12/3 in between the 2 switches. you can also use 14 gauge wire
yes like a hall light.
not enough information what type of vehicle does it have a idiot light or gauge
If you wire the lights in parallel you can then decide on any switch to control any light
Bare copper wire is often used as a ground in electrical applications such as light switches and outlets.
See view discussion below.
Why, if you need two switches to operate one fixture,you install two three way switches, the switch comes with a wiring diagram. You will also need to wire with 12/3wgr, this has 4 wires.
just run a wire from add-on to dashlight fuse in you fuse panel
If your wiring it up for a light switch, then you will need 2 3 way switches, this will allow you to turn on and off lights from 2 locations
That will only work if there are two ballasts in the unit.
Three wire strand running between 2 switches is for a 3 way switch. It is only one side of the circuit. Since it is only one side and switches between the 3 wires there is no way to use it for a light. There may be power at the hall light, but I have seen all types of wiring and each circumstance has to be looked at on it's own.
This is done using two two-way switches, switches with two switching position. The input live wire from the circuit breaker goes to the middle point of one switch. The output live wire to the light is connected to the middle point of the second switch. The two remaining points from one switch are then connected to the two remaining points on the other switch. The neutral from the light goes straight to the neutral bar in the Distribution Board.
You need a wire that u can link to 3 ways then link them to 3 light switches anywhere in your house the farther the more.
Sure; the fan has 3 wires so you can wire the light and fan separately, but if you don't have that option, you don't NEED to put the fan and the light on separate switches. You can always turn the light or fan on/off using the pull strings.
To help you out, it is called a three way light switch. See Related Links below.
Power coming into the box powering all 3 switches. A 12/2 or 14/2 wire going to each light from each switch depending on the size power wire you are using. They must be the same size wire. All the whites tied together and pushed back in the box. All the grounds tied together with a long jumper wire going to the ground screw of each switch. The black power wire connected to all three switches (bottom screw) with a long jumper wire. The black wires from each light connected to the 3 individual switches (top screw).
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
wire each switch to each light...
That is called 4 way intermediate switch wiring. Click the link to watch a video I have posted showing how to wire just such a circuit.
No, you can feed it with a 2 wire Romex + ground. It depends on what is mounted on the ceiling. If it is just a light all you need is 2 wire + ground Romex. However if it is a fan/light and you want to control each one independant of the other you will need to use 3 wire Romex + ground. This is of course if you have 2 seperate switches. You would then connect the red wire to the blue light wire and the black wire to the black fan wire. If you use 2 wire Romex just connect the blue and black fan/light wire to the black wire in the ceiling box.
You will need two 3/way switches and two 4/way (Intermediate) switches. Click the link to see a video of exactly how to wire such a circuit.
Connect the incoming power to the line side of the GFCi outlet. Now run another wire connected to the line side of the GFCI outlet from the GFCI outlet to the switches. Power one of the switches and use that switch to turn on the 2 lights. Run power from that switch to another switch and use that switch to send power to the fan. Mount both switches in a double pole switch box. If the light above the sink has an outlet on it then you will have to connect power going to that light on the load side of the GFCI outlet. If not then just connect it to the line side.
A 3way switch at each location is what you use, but it must be wired properly to work. You must have incoming power at one switch location and no power at the other location. The other location has the wire going up to the light. You then need a 3 conducted wire such as 12/3 or 14/3 running between the switches. Use the same size wire you used to power the switch and top up to the light. You then connect the black power wire at one location to the black screw on the switch, and at the other location you connect the black wire going to the light to the black screw on that switch. At each location tie the whites together under a wire nut and shove that back in the box. Tie the grounds together and connect that to the ground screw at each switch. At each location you will now have the black and red wire from the wire you ran between the switches left. Those are called travelers. Connect those wires to the remaining 2 screws left on the switches at each location. Does not mater which you connect to which screw. Assuming no other wires are involved this is how you wire it.
