Composite Connectors, Part 1

Disclaimer

• Recommendations are not universal; they are starting points to begin your own efforts.
• No information here replaces the advice of a professional.
• Document, label, and test your wiring harnesses!
• Test your crimps!

Reading Entries

• Name: an abbreviation for what the pin does. This is for identification only.
• Pin #: order of the pin in the connector.
• Color: optional color-coding for the wire insulation.
  • Colors are solely to help visual identification.
  • Colors do not always match the wire colors that usually tail a component; this is meant to maintain internal consistency.

See the tips page for details.

Composite connectors may not be the technical term for connectors with pins that lead to multiple endpoints, but I have not found the correct one.
