What are the 2 red wires for on a aftermarket backup camera?
The red wire passes the reverse signal up to the front of the car. The camera end has a red and black wire which the red wire gets connected to the reverse light and the black gets connected to ground.
The red and the black are the positive and negative respectively. The blue wire is a trigger. This is how it works : For the monitor to work as a mirror when you are not backing up it should be turned OFF. If it were turned ON then all you would see is a blue screen.

What should the red wire be connected to?
Red wires are mostly used to connect the home’s power system, and hardwired smoke detectors such that if one alarm goes off, all of them go off. Red wires are used in the installation of ceiling fans, where the light switches may be. Electricians can link a red and black wire or two red wires.
Does the red wire go on top or bottom?
If the terminal isn’t labeled as “Common,” it will have a black or copper terminal on the bottom side of the switch. Then, connect the red wire to a terminal on the top side of the switch. Red is a traveler wire and can be connected to the left or the right upper terminal.
Where do you wire red wire?
Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.
Where does the red wire go on a 3 way?
The red wires connect to the top of the switch. Make sure to connect it to the same location, either the upper right or left side in both boxes. There is a second traveler wire in both boxes, and it’s time to connect those.
How do you know which wire is hot on 3-way?
Is 2 way and 3-way switch the same?
Much like the two-way switch, a three-way switch turns a light on or off. However, there is a crucial difference. The three-way switch is used in conjunction with another three-way switch. Each one of them has the power to interrupt the electrical flow and turn the light off from a different part of the room.
Where does the red and black wire go on a 3-way switch?
Three-way wire(which includes red, black and white wires) runs from the switch on the left to the switch on the right, with the white wire carrying ground and the red and black wires carrying the output from terminals in the left switch. Normal sheathed cable runs from the right switch to the light.
Do I wire red and black together?
Red and black wires are both hot or line wires and should not be connected together.
Does red wire go to blue or black?
Connect black fan wire to the black ceiling wire. Connect the blue wire to the red wire. Connect white wires together. Connect green/bare copper wires.
Is there always a hot wire on a 3-way switch?
Wiring for a 3-Way Switch
The most important wire to get right is the one connected to each switch’s common screw terminal. This is the “hot” wire (usually colored black, but not always), and it brings the power from the source and delivers it to the first switch and then from the second switch to the light fixture.
What happen when a 3 way switch is improperly wired?
If your three-way switch is wired wrong your light will not work from both locations. It will only work from one location.
How can you tell if a wire is load or a three way switch?
The line is usually a black insulated wire that goes to the bottom of the switch while the load is a red wire that goes to the top of the switch. Alternatively, you may use a voltage tester or multimeter to check for a voltage reading from one of the wires.
How do I know if my 3 way switch is wired wrong?
Follow these steps to find which switch is bad.
Toggle each switch until the light come on. Toggle one switch to see if it turns the light on and off. If it does, it is a good switch.
Toggle the other switch to see if it turns the light on and off. If it does, it is a good switch and the other is bad.
What happens if you wire a 3 way switch backwards?
As earlier answers have said reversing the connections to L1 and L2 on one switch will result in your light being off when both switches are down. However it will also be off when both are up and the light will only illuminate when the switches are positioned differently.
What happens if you connect the wrong wires on a switch?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
Which wire goes to the black screw on a 3 way switch?
Tighten the terminal screws. Connect the ground wire to the green screw, then connect the wire marked common to the black or dark colored screw. Connect the two remaining traveler wires to the two brass or light colored screws.
