Connector wire direction and size

When designing an electrical circuit, either when prototyping or designing a footprint for electrical CAD software, or when designing an enclosure, make sure to have reference parts, both in order to take accurate measurements, and to determine the direction of wires or pins protruding from said connector. Spacing between parts and connectors is important, as well as placement of connectors on board or panel. A mock-up of the assembly will most likely be a sure-fire way to avert future mistakes and valuable time invested in correction.
