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.

For trailer wiring I recommend installing a 7 way so you can operate the light inside the trailer. The 7 way wiring I recommend is the Hopkins # H20046. This harness is an 8 ft long molded 7 way. I then recommend using a junction box like part # 38656. You would mount this on your trailer and then run your # H20046 wiring into the box. You can...
Wiring Configurations: line switch switch load If your wiring is like either diagram below, you can wire your smart switch in either of your two switch boxes. Having multiple lights wired in parallel will not change your wiring. You should only need to change the wiring in each switch box (light box(es) do not need to be touched).
My '92 GMC Sierra had a 6 pin trailer harness connector and I'm going to be pulling a pop up camper in a few weeks that has a 7 pin connector. I originally ordered a 47435 6 Pole to 7 Pole Trailer Wiring Adapter. After thinking about it for a day I changed my mind and ordered a HM48470 Hopkins Endurance Multi tow 7 way, 5 & 4 wire Flat Connector to mount in the bumper and a HM47570 Hopkins ...

The meter must be zeroed if the resistance range is changed. Measured resistance values will be inaccurate if unable to properly zero the meter. In the example picture, the meter indicates 0.2 ohms resistance or zero. The meter can not display a value lower than this value, since there is no zero adjust feature it is considered 0.
