CARGO LAMP
Cherokee-Wagoneer Models
The cargo lamp is located in the rear headlining and
controlled by the headlamp switch, door switches, and

cargo lamp switch. The cargo lamp switch may be oper
ated from the rear of the vehicle after lowering the
tailgate glass. The cargo lamp switch provides an addi
tional ground switch for the cargo lamp.
NOTE: The cargo lamp on the Truck models is ad
dressed in the exterior lighting system section of this
chapter.
GLOVE BOX LAMP
Current passes from the stoplight switch feed to the
glove box lamp socket. The glove box lamp switch is
grounded to the instrument panel and thus has no
ground wire. When the glove box is open, the switch
completes the ground circuit through the instrument
panel. Refer to Wiring Diagrams at the end of this
manual for details.
INSTRUMENT CLUSTER LAMPS
The instrument cluster lamps are covered in detail in
Chapter 3C.

Main Harness Connector
All models have a main wiring harness connector lo
cated at the left upper corner of the dash panel. This
connector is made up of the engine and forward lamp
harness at the engine compartment and the fuse and
instrument panel harness at the passenger com
partment side.
The connector can be removed from the dash panel by
removing the center bolt from the engine compartment
side and the two attaching screws from the driver's side.
Be careful not to bend the male spade terminals when
removing or installing the connector. The center of the
connector is filled with a non-conductive grease to pre
vent corrosion of the terminals. If any wires are re
placed on the engine compartment side, the terminal
opening must be resealed with a durable waterproof
sealer. Do not use string-type body caulk as a sealer.
Fusible Links
Fusible links are harness wires covered with a special
non-flammable insulation. The links protect circuits

which are not normally fused due to carrying high am
perage loads or because of their location in the chassis.
They are used to prevent major harness damage in the
event a short circuit, short to ground or overload condi
tion occurs.
All Jeep models are equipped with fusible links, lo
cated in the engine compartment, which protect the
circuits shown in the Wiring Diagrams.
Each link is of a fixed value for the specific load.
Replacement links are listed in the parts catalog.
NOTE: Failure of a fusible link is often caused by a
grounded circuit; therefore, the cause of the failure
must be determined prior to installing a new link.
Fusible Link Replacement
(1) Disconnect battery negative cable.
(2) Follow one end of the link to the terminal end.
Follow the remaining end to wire harness.
(3) Remove harness tape approximately 2 inches
from where link enters harness; the soldered splice will
be visible.
(4) Following the wiring diagram, determine which
circuit(s) may have caused the failure. Test the circuit(s)
