Weather Pack(R) terminals
Some terminals do not require all of the steps shown. Skip the steps that do not apply for your immediate terminal repair. The J 38125-B contains further
information.
1. Cut off the terminal between the core and the insulation crimp. Minimize any wire loss. For Weather Pack(R) terminals, remove the seal.
2. Apply the correct seal per gage size of the wire. For Weather Pack(R) terminals, slide the seal back along the wire in order to enable insulation
removal.
3. Remove the insulation.
4. For Weather Pack(R) terminals only, align the seal with the end of the cable insulation.
5. Position the strip in the terminal
For Weather Pack(R) terminals, position the strip and seal in the terminal.
6. Hand crimp the core wings.
7. Hand crimp the insulation wings.
For Weather Pack(R) terminals, hand crimp the insulation wings around the seal and the cable.
8. Solder all of the hand crimp terminals.
Terminal Position Assurance Locks
The terminal position assurance (TPA) insert resembles the plastic combs used in the control module connectors. The TPA keeps the terminal securely
seated in the connector body. Do not remove the TPA from the connector body unless you remove a terminal for replacement.
