Difference between wiring diagram, schematic, and Pictorial diagram
A schematic shows the plan and function of an electrical circuit however is not concerned with the physical design of the wires. Wiring diagrams demonstrate how the wires are connected, where they ought to be found in the device and the physical connections in between all the elements.
Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components. Pictorial diagrams are typically pictures with labels or highly-detailed drawings of the physical parts.
