Connector Repairs contains a list of all connector repairs. The connector repairs are listed by the connector manufacturer and then by connector type. If the technician cannot identify the manufacturer of the connector, refer to Identifying Connectors below. Knowing the connector manufacturer will assist in finding the correct connector repair from the following list:

    •  Connector Position Assurance Locks
    •  Terminal Position Assurance Locks
    •  Bosch Connectors
    •  Delphi Connectors
    •  Tyco/AMP Connectors
    •  Yazaki Connectors

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.


Object Number: 1466850 Size: SH
    • Most of AFLs connectors have EPC on their connector body. Some of the smaller connectors will not have any markings on them.

Object Number: 1460356 Size: SH
    • In some cases Bosch will actually be printed on the connector. If Bosch does not appear on the connector, look for the Bosch logo. The Bosch logo is a circle with a blunted arrow inside. This logo can appear anywhere on the connector and is often very small.

Object Number: 1460486 Size: SH
    • In some cases Delphi will actually be printed on the connector. If Delphi is not printed on the connector, look for PED. In both cases there is no specific orientation for Delphi or PED and they can appear anywhere on the connector.

Object Number: 1460611 Size: SH
    • FCI connectors may have the FCI logo on their connectors. The logo is the letters FCI with an "A" above it.

Object Number: 1468768 Size: SH
    • JAE connector have JAE in small letters on their connectors.

Object Number: 1468706 Size: SH
    • JST connectors have JST in small letters on their connectors, similar to that above. The location of the logo will vary with the connector size and style.

Object Number: 1709340 Size: SH
    • Kostel has an "LK" with a circle around it. These connector are usually used as a transmissions connection.

Object Number: 1467199 Size: SH
    • Most Molex connectors will have the Molex logo on the dresscover of the connector. In some cases the connectors may have MX followed by another letter. The third letter indicates where the connector was made. A connector with MXD is a Molex connector made in Detroit.

Object Number: 1467225 Size: SH
    • Sumitomo has a unique symbol on their connector and possibly a part number. The symbol is similar to that of a diamond lying on its side, similar to that shown. The logo could appear anywhere but the most common place is at the wire side of the housing.
    • Tyco/AMP has many different and unique connector designs. Some may or may not have identifiable marks on them.

Object Number: 1467254 Size: SH
    • Yazaki has a wedge or arrow shape, similar to that shown.
