Delphi Connectors Weather Pack

Special Tools

For equivalent regional tools, refer to Special Tools.

The following is the proper procedure for the repair of Weather Pack® Connectors.


    Object Number: 8802  Size: SH
  1. Separate the connector halves (1).
  2. Open the secondary lock. A secondary lock aids in terminal retention and is usually molded to the connector (1).
  3. Grasp the wire and push the terminal to the forward most position. Hold the wire in this position.

  4. Object Number: 8803  Size: SH
  5. Insert the Weather Pack® terminal removal tool EL-38125-10A into the front (mating end) of the connector cavity until it rests on the cavity shoulder (1).
  6. Gently pull on the wire to remove the terminal through the back of the connector (2).
  7. Note: Never use force to remove a terminal from a connector.

  8. Inspect the terminal and connector for damage. Repair as necessary. Refer to Repairing Connector Terminals.
  9. Reform the lock tang (2) and reset terminal in connector body.
  10. Close secondary locks and join connector halves.
  11. Verify that circuit is complete and working satisfactorily.
  12. Perform system check.

Terminated Lead Repair

  1. Remove the terminal.
  2. Find the appropriate terminated lead.
  3. Use the appropriate splice sleeves depending on the gage size.
  4. Refer to Splicing Copper Wire Using Splice Sleeves.

Delphi Connectors Push To Seat

Special Tools

For equivalent regional tools, refer to Special Tools.

Terminal Removal

Follow the steps below in order to repair push to seat connectors.

  1. Remove the terminal position assurance (TPA) device, the connector position assurance (CPA) device, and/or the secondary lock.

  2. Object Number: 8802  Size: SH
  3. Separate the connector halves (1).

  4. Object Number: 8803  Size: SH
  5. Use the proper pick or removal tool (1) in order to release the terminal.
  6. Gently pull the cable and the terminal (2) out of the back of the connector.

  7. Object Number: 8804  Size: SH
  8. Re-form the locking device if you are going to reuse the terminal (1).
  9. To repair the terminal, refer to Terminal Repair.

Reinstalling Terminal

  1. In order to reuse a terminal or lead assembly, refer to Wiring Repairs.

  4. Install the TPA, CPA, and/or the secondary locks.

Terminated Lead Repair

  1. Remove the terminal.
  2. Find the appropriate terminated lead.
  3. Use the appropriate splice sleeves depending on the gage size.
  4. Refer to Splicing Copper Wire Using Splice Sleeves.

Delphi Connectors Pull To Seat

Special Tools

For equivalent regional tools, refer to Special Tools.

Terminal Removal

If the terminal is visibly damaged or is suspected of having a faulty connection, the terminal should be replaced.

Follow the steps below in order to repair pull-to-seat connectors:


    Object Number: 904718  Size: SH
  1. Remove the connector position assurance (CPA) device and/or the secondary lock.
  2. Disconnect the connector from the component or separate the connectors for in-line connectors.
  3. Remove the terminal position assurance (TPA) device.
  4. Insert the proper pick or removal tool into the front of the connector body.
  5. Note: On connectors with more than one terminal the service loop may not be large enough to remove the terminal and crimp on a new one. If the terminal wire does not have a large enough service loop for removal, cut the wire 5 cm (2 in) behind the connector before removal.

  6. Grasp the wire at the back of the connector body and gently push the terminal out the front of the connector body.

Terminal Repair

  1. If the wire needed to be cut in order to remove the terminal, gently push a small length of the same size wire through the back of the connector cavity until there is enough wire exposed in order to crimp on a new terminal. If the wire was not cut, cut the existing wire as close to the old terminal as possible.
  2. Strip 5 mm (3/16 in) of insulation from the wire.
  3. Crimp a new terminal to the wire.
  4. Solder the crimp with rosin core solder.

Terminal Installation

  1. Align the terminal and pull the wire from the back of the connector in order to seat the terminal.
  2. If necessary, cut the new wire to proper length and splice with existing circuit. Refer to Splicing Copper Wire Using Splice Sleeves.
  3. If the connector is outside of the passenger compartment, apply dielectric grease to the connector.
  4. Install the TPA, CPA, and/or the secondary locks.

Terminated Lead Repair

  1. Remove the terminal.
  2. Find the appropriate terminated lead.
  3. Use the appropriate splice sleeves depending on the gage size.
  4. Refer to Splicing Copper Wire Using Splice Sleeves.

Delphi Connectors Micro-Pack 100W

Special Tools

For equivalent regional tools, refer to Special Tools.

Terminal Removal Procedure

There are 2 styles of Micro-Pack 100W connectors. These connectors are very similar but use different terminals and have some minor physical differences also.


Object Number: 1364951  Size: SH

The first connector design of the Micro-Pack 100W (1) has a white connector interface that holds the terminals. The second design of the Micro-Pack 100W (2) has a gray interface to hold the terminals. Also, the first design has terminal cavities that are further apart (3 mm centerline) and offset from the other row of terminal cavities in the connector. The second design has terminals cavities that are closer together (2.54 mm centerline) and aligned vertically. One other way to identify the second design is the thin strip of material that runs along the outside of the cavities.


Object Number: 1364942  Size: SH

Note: There are 2 styles of Micro-Pack 100W terminals which are very similar. Ensure that you have the correct terminal before crimping the new terminal to the wire. The first design connector uses the longer terminal (1) that has a raised area in front of the recess in the terminal. The second design connector uses the shorter terminal without the raised area.

Follow the steps below in order to remove terminals from Micro-Pack 100W connectors. Some Micro-Pack 100W connector disassembly procedures will vary. Use this procedure as a guide.

  1. Disconnect the connector from the component.

  2. Object Number: 880994  Size: SH
  3. Locate the nose piece locking tabs that are positioned on the side of the connector nose piece. The connector nose piece acts as a terminal positive assurance (TPA) and may be referred to as such.

  4. Object Number: 881004  Size: SH
  5. Use a small flat-blade tool to push in one of the locking tabs while gently pulling on the same side of the nose piece.
  6. Repeat the procedure for the other locking tab and remove the nose piece.
  7. Remove the wire dress cover. The following is a general procedure for wire dress cover removal. Use this procedure as a guide, some dress cover removal procedures may vary.

  8. Object Number: 881006  Size: SH
  9. Use fingers to squeeze the 2 locking legs of the cover.

  10. Object Number: 881008  Size: SH
  11. Apply pressure and gently rock the cover until one locking leg is unseated.

  12. Object Number: 881011  Size: SH
  13. Continue to apply pressure and rock the cover until the second locking leg is unseated. Repeat procedure for the other side of the dress cover and remove the cover.

  14. Object Number: 881017  Size: SH
  15. Use EL-38125-12A to gently lift the terminal retaining tab while gently pulling the wire out of the back of the connector. Always remember never use force when pulling a terminal out of a connector.
  16. If the terminal is severely bent or damaged, it may be possible on some connectors to push the wire out of the front of the connector instead of pulling it through. This will prevent damage to the internal seals of the connector. Once the terminal is pushed out of the connector, cut the wire as close to the terminal as possible and pull the wire through the connector.

Terminated Lead Repair

  1. Remove the terminal.
  2. Find the appropriate terminated lead.
  3. Use the appropriate splice sleeves depending on the gage size.
  4. Refer to Splicing Copper Wire Using Splice Sleeves.

Terminal Replacement Procedure

After the terminal is crimped to the wire perform the following procedure in order to replace Micro-Pack 100 terminals.

  1. Slide the new terminal into the correct cavity at the back of the connector.
  2. Push the terminal into the connector until it locks into place. The new terminal should be even with the other terminals. Ensure that the terminal is locked in place by gently pulling on the wire.
  3. To assemble the connector, reverse the Terminal Removal Procedure.
