(2) Insert the removed wire in the same cavity on
the repair connector.
(3) Repeat steps for each wire in the connector,
being sure that all wires are inserted into the proper
cavities. For additional connector pin-out identifica-
tion, refer to the wiring diagrams.

ing tab must be placed in the locked position to pre-
vent terminal push out.
(5) Connect connector to its mating half/compo-
nent.
(6) Connect battery and test all affected systems.
CONNECTOR - MOLEX
REMOVAL
(1) Disconnect battery.

(4) Using special tool 6742, release the locking fin-
gers on the terminal (Fig. 11).
(5) Pull on the wire to remove it from the connec-
tor.
(6) Repair or replace the terminal as necessary.
INSTALLATION
(1) Reset the terminal locking tang.
(2) Insert the removed wire in the same cavity on
the repair connector.
(3) Repeat steps for each wire in the connector,
being sure that all wires are inserted into the proper
cavities. For additional connector pin-out identifica-
tion, refer to the wiring diagrams.(4) Connect connector to its mating half/compo-
nent.
(5) Connect battery and test all affected systems.
CONNECTOR - THOMAS AND
BETTS
REMOVAL
(1) Disconnect battery.
(2) Disconnect the connector from its mating half/
component.
(3) Push in the two lock tabs on the side of the
connector (Fig. 12).

(4) Insert the probe end of special tool 6934 into
the back of the connector cavity (Fig. 13).
(5) Grasp the wire and tool 6934, then slowly
remove the wire and terminal from the connector.
(6) Repair or replace the terminal as necessary.
INSTALLATION
(1) Reset the terminal locking tang.
(2) Insert the removed wire in the same cavity on
the repair connector.
(3) Repeat steps for each wire in the connector,
being sure that all wires are fully seated into the
proper cavities. For additional connector pin-out
identification, refer to the wiring diagrams.
(4) Push in the single lock tab on the side of the
connector (Fig. 14).
(5) Connect connector to its mating half/compo-
nent.
(6) Connect battery and test all affected systems.
DIODE
REMOVAL
(1) Disconnect the battery.
(2) Locate the diode in the harness, and remove
the protective covering.
(3) Remove the diode from the harness, pay atten-
tion to the current flow direction (Fig. 15).
INSTALLATION
(1) Remove the insulation from the wires in the
harness. Only remove enough insulation to solder in
the new diode.
(2) Install the new diode in the harness, making
sure current flow is correct. If necessary, refer to the
appropriate wiring diagram for current flow (Fig. 15).
(3) Solder the connection together using rosin core
type solder only.Do not use acid core solder.
(4) Tape the diode to the harness using electrical
tape. Make sure the diode is completely sealed from
the elements.
(5) Re-connect the battery and test affected sys-
tems.

TERMINAL
REMOVAL
(1) Disconnect battery.
(2) Disconnect the connector being repaired from
its mating half/component.
(3) Remove the connector locking wedge, if
required (Fig. 16).
(4) Position the connector locking finger away from
the terminal using the proper pick from special tool
kit 6680. Pull on the wire to remove the terminal
from the connector (Fig. 17) (Fig. 18).(5) Cut the wire 6 inches from the back of the con-
nector.
INSTALLATION
(1) Select a wire from the terminal repair assem-
bly that best matches the color wire being repaired.
(2) Cut the repair wire to the proper length and
remove one±half (1/2) inch of insulation.
(3) Splice the repair wire to the wire harness .
(4) Insert the repaired wire into the connector.
(5) Install the connector locking wedge, if required,
and reconnect the connector to its mating half/compo-
nent.
(6) Re-tape the wire harness starting at 1±1/2
inches behind the connector and 2 inches past the
repair.
(7) Connect battery and test all affected systems.
WIRE
STANDARD PROCEDURE - WIRE SPLICING
When splicing a wire, it is important that the cor-
rect gage be used as shown in the wiring diagrams.
(1) Remove one-half (1/2) inch of insulation from
each wire that needs to be spliced.
(2) Place a piece of adhesive lined heat shrink tub-
ing on one side of the wire. Make sure the tubing will
be long enough to cover and seal the entire repair
area.
(3) Place the strands of wire overlapping each
other inside of the splice clip (Fig. 19).
(4) Using crimping tool, Miller p/n 8272, crimp the
splice clip and wires together (Fig. 20)

(5) Solder the connection together using rosin core
type solder only (Fig. 21).
CAUTION: DO NOT USE ACID CORE SOLDER.(6) Center the heat shrink tubing over the joint
and heat using a heat gun. Heat the joint until the
tubing is tightly sealed and sealant comes out of both
ends of the tubing (Fig. 22).
