Cutting Wires (7) Remove 1 inch of insulation from each wire.
(8) Place a piece of heat shrink tubing over one
side of the wire. Make sure the tubing will be long
enough to cover and seal the entire repair area.
(9) Spread the strands of the wire apart on each
part of the exposed wires (Fig. 7 example 1).
(10) Push the two ends of wire together until the
strands of wire are close to the insulation (Fig. 7 exam­
ple 2).
(11) Twist the wires together (Fig. 7 example 3).
(12) Solder the connection together using rosin
core type solder only. Do not use acid core solder.
(13) 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. (14) Repeat steps 8 thru 13 for each wire.
(15) Re-tape the wire harness starting 1-1/2 inches
behind the connector and 2 inches past the repair. (16) Reconnect the repaired connector.
(17) Connect battery and test all affected systems.

TERMINAL
REPLACEMENT
(1) Disconnect battery.
(2) Disconnect the connector being repaired form
its mating
half.
(3) Remove connector locking wedge (Fig. 8).
(4) Position the connector locking finger away from
the terminal. Pull on the wire to remove the termi­ nal from the connector (Fig. 9).
(5) Cut the wire 6 inches from the back of the con­
nector. (6) Remove 1 inch of insulation from the wire on
the harness side.
(7) Select a wire from the terminal repair assem­
bly that best matches the color wire being repaired. (8) Cut the repair wire to the proper length and re­
move 1 inch of insulation.
(9) Place a piece of heat shrink tubing over one of
side of the wire. Make sure the tubing will be long
enough to cover and seal the entire repair area.
(10) Spread the strands of the wire apart on each
part of the exposed wires (Fig. 7 example 1). (11) Push the two ends of wire together until the
strands of wire are close to the insulation (Fig. 7 ex­
ample 2).
(12) Twist the wires together (Fig. 7 example 3).
(13) Solder the connection together using rosin
core type solder only. Do not use acid core solder.
(14) 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.
(15) Insert the repaired wire into the connector.
(16) Install the connector locking wedge and recon­
nect the connector to its mating
half.

(17) Re-tape the wire harness starting 1-1/2 inches
behind the connector and 2 inches past the repair. (18) Connect battery and test all affected systems.

SYMBOLS
AND
FUSES
Various symbols are used throughout wiring dia­
grams. These symbols can be identified by referring
to symbol identification chart (Fig. 11). For fuse block and relay bank information refer to
(Fig. 12).

CAUTION:
When replacing
a
blown fuse,
it is
impor­

tant
to
replace
it
with
a
fuse having
the
correct
am­
perage rating.
The use of a
fuse
with
a
rating other
than indicated
may
result
in a
dangerous
electrical
overload.
If a
proper
rated
fuse continues
to
blow,
it
indicates
a
problem
that
should
be
corrected.
