Identifying Connectors

Knowing the connector manufacturer is helpful when trying to locating the correct connector repair procedure. There are many different connector designs used on GM vehicles and it is sometimes difficult to identify the connector manufacturer. The information in this document should help with the identification of connector manufactures.

The following connector manufacturers make most of the connectors found in GM vehicles:

    • AFL/EPC (Alcoa Fujikura Ltd./Engineered Plastics Components)
    • Bosch
    • Delphi
    • FCI (Framatome Connectors International)
    • JAE (Japan Aviation Electronics)
    • JST (Japan Solderless Terminals)
    • Kostel
    • Molex
    • Sumitomo
    • Tyco/AMP
    • Yazaki

Identifying the manufacturer of a connector is often difficult. When trying to determine the manufacturer of a connector, look for specific identifying marks that are unique to that connector supplier. Most of these identify marks are hard to find or see. Check the connector carefully and refer to the information below for pictures and descriptions of connector identification markings.
