WEATHER-PACK CONNECTOR

Tools Required

5-8840-0388-0 Weather-Pack II Terminal Remover

Removal

A Weather-Pack connector can be identified by a rubber seal
at the rear of the connector. This engine room connector
protects against moisture and dirt, which could form oxidation
and deposits on the terminals. This protection is important,
because of the low voltage and the low amperage found in the
electronic systems.

1.  Open the secondary lock hinge on the connector.

2.  Use tool 5-8840-0388-0 or the equivalent to remove the

pin and the sleeve terminals. Push on 5-8840-0388-0 to
release.

Notice: Do not use an ordinary pick or the terminal may be
bent or deformed. Unlike standard blade terminals, these
terminals cannot be straightened after they have been
improperly bent.

3.  Cut the wire immediately behind the cable seal.

Installation

Make certain the connectors are properly seated and all of the
sealing rings are in place when you reconnect the leads. The
secondary lock hinge provides a backup locking feature for the
connector. The secondary lock hinge is used for added
reliability. This flap should retain the terminals even if the small
terminal lock tangs are not positioned properly.
Do not replace the Weather-Pack connections with standard
connections. Read the instructions provided with the Weather-
Pack connector and terminal packages.

1.  Replace the terminal.

2.  Slip the new seal onto the wire.

3.  Strip 5mm (0.2”) of insulation from the wire.

4.  Crimp the terminal over the wire and the seal.

5.  Push the terminal and the connector to engage the

locking tangs.

6.  Close the secondary locking hinge.

COM-PACK III

The Com-Pack III terminal looks similar to some Weather-Pack
terminals. This terminal is not sealed and is used where
resistance to the environment is not required. Use the standard
method when repairing a terminal. Do not use the Weather-
Pack terminal tool 5-8840-0388-0 or equivalent. These will
damage the terminals.

METRI-PACK

Tools Required

5-8840-0632-0 Terminal Remover

Removal

Some connectors use terminals called Metri-Pack Series 150.
These may be used at the engine coolant temperature (ECT)
sensor.

1.  Slide the seal (1) back on the wire.

2.  Insert the 5-8840-0632-0 tool or equivalent (3) in order to

release the terminal locking tang (2).

3.  Push the wire and the terminal out through the connector.

If you reuse the terminal, reshape the locking tang.

Installation

Metri-Pack terminals are also referred to as  "pull-to-seat"
terminals.

1.  In order to install a terminal on a wire, the wire must be

inserted through the seal (2) and through the connector
(3).

2.  The terminal (1) is then crimped onto the wire.

3.  Then the terminal is pulled back into the connector to

seat it in place.
