A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

Went camping and came back and the trailer wiring is totally meted. I opened up the new connector and it's wired backwards. Ie pins 4 and 1 are reversed and 6 and 7 and 2 and 5. Would this cause the wiring to melt in the trailer? Just got back to taking trailer and car to sparky tomorrow. Reply

The 4 pin standard flat style connector has four contacts with a male pin on the vehicle side for the ground. Wiring the 4 pin connector You will need a volt meter and a cutting plier to splice the wires. Turn on the running lamps of your vehicle. Probe the wiring to determine which of the wire that leads to the taillight is for the running lamp.
Custom wiring is the ideal solution for installing trailer light wiring on your vehicle. A custom wiring harness or 'T connector' is a vehicle specific harness that plugs in without any spicing required and provides a standard connector output, such as a 4 way flat.
