1995 JEEP YJ diagram

In the WIPE or WASH positions, the rear wiper
switch supplies voltage to the wiper motor on circuit
V13. Circuit Z1 provides ground for the wiper motor.
The rear windshield washer uses a pump motor lo-
cated inside the windshield washer fluid reservoir.
When the rear wiper switch is pressed, power is sup-
plied through the wiper switch to both the rear wiper
and the pump motor on circuit V20. Circuit Z1 pro-
vides ground for the pump motor.
As the rear wiper motor turns, the park switch, in-
ternal to the motor, moves from the RUN position to
the PARK position. When the wiper switch is turned
OFF, the F20 circuit prevents the wipers from stop-
ping in any position but park.DIAGRAM INDEX

TRAILER TOW
TRAILER TOW
The factory installed trailer tow system in this ve-
hicle uses three relays and a circuit breaker along
with the trailer tow wiring connector located below
the rear bumper.
Battery voltage for the trailer tow circuit breaker
and relays is supplied on circuit A11. This circuit is
HOT at all times and connects to the power accessory
tap in the fuse block. An in line 10 amp circuit pro-
tected breaker protects circuit A11 and the trailer
tow circuits. The trailer tow circuit breaker is located
in the left rear quarter panel.
STOP LAMP RELAY
Power for the coil side of the stop lamp relay is
supplied by circuit L50. This circuit connects to the
stop lamps. Ground for the coil side is supplied on
circuit Z1.
When the operator depresses the brake pedal, volt-
age flows through the coil of the relay to ground
causing the contacts in the relay to connect circuits
A11 and 95.
Circuit 95 connects to the left and right turn signal
relays. Voltage flows through the closed contacts in
the relays to the trailer tow connector.
RIGHT TURN RELAY
Power for the coil side of the right turn relay is
supplied by circuit L60. This circuit connects to the
right side turn signal lamps. Ground for the coil side
of the relay is supplied on circuit Z1.
When the operator turns the right turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L60.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L60 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.
The A11 circuit is HOT at all times and protected by
a 10 amp circuit breaker located in the left rear
quarter panel.
LEFT TURN RELAY
Power for the coil side of the left turn relay is sup-
plied by circuit L61. This circuit connects to the left
side turn signal lamps. Ground for the coil side of the
relay is supplied on circuit Z1.
When the operator turns the left turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L61.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L61 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.
The A11 circuit is HOT at all times and protected by
a 10 amp circuit breaker located in the right rear
quarter panel.

POWER DOOR LOCKS
POWER DOOR LOCKS
Two relays provide power for the power door lock
motors. The Unlock relay provides power for the un-
lock circuits while the Lock relay powers the lock cir-
cuits. Either the power door lock switches or the
remote keyless entry module operate the Unlock and
Lock relays.
LOCK RELAY
Circuit M1 from fuse 9 in the fuse block powers cir-
cuit P38. When either power door lock switch is put
in the LOCK position, the switch connects circuit P38
to circuit P35. If the operator uses Remote Keyless
Entry (RKE), the RKE module powers circuit P35. In
either case, circuit P35 supplies power to the coil side
of the lock relay, causing the relay contacts to close.
Circuit Z1 provides ground for the coil side of the
lock relay.
When the lock relay contacts close, they connect
battery voltage from circuit P37 to circuit P2. Circuit
P2 then supplies battery voltage to the power door
lock motors to LOCK the doors.
When the power doors LOCK, ground for the mo-
tors is on circuit P34 through the normally closed
contacts in the door unlock relay to ground on circuit
Z1.
UNLOCK RELAY
Circuit M1 from fuse 9 in the fuse block powers cir-
cuit P38. When either power door lock switch is put
in the UNLOCK position, the switch connects circuit
P38 to circuit P36. If the operator uses Remote Key-
less Entry (RKE), the RKE module powers circuit
P36. In either case, circuit P36 supplies power to the
coil side of the unlock relay, causing the relay con-
tacts to close. Circuit Z1 provides ground for the coil
side of the unlock relay.
When the unlock relay contacts close, they connect
battery voltage from circuit P37 to circuit P34. Cir-
cuit P34 then supplies battery voltage to the power
door lock motors to UNLOCK the doors.
When the power doors UNLOCK, ground for the
motors is on circuit P2 through the normally closed
contacts in the door lock relay to ground on circuit
Z1.
REMOTE KEYLESS ENTRY MODULE
Circuit M1 from the ignition off draw (IOD) fuse in
cavity 9 of the fuse block supplies power to the Re-
mote Keyless Entry (RKE) module. Circuit F87 from
fuse 17 in the fuse block supplies power to the RKE
module when the ignition switch is in the START or
RUN position. Circuit Z1 provides ground for the
RKE module.
The RKE module UNLOCKS the doors by energiz-
ing the unlock relay on circuit P36. Refer to Unlock
Relay.
The module LOCKS the doors by energizing the
lock relay on circuit P35. Refer to Lock Relay.
