Blunt cut ignition controlled power
and signal circuits are also included
in the wire coiled under the
instrument panel near the center of
the vehicle. They include:
.*A yellow, 0.5 mm² (20 gauge)
circuit, Hot in ACCESSORY,
RUN or RAP (Retained
Accessory Power).
.A pink, 0.5 mm² (20 gauge)
circuit, Hot in START and RUN.
(7A maximum load)
.*A yellow/black, 0.5 mm²
(20 gauge) transmission park
signal. This circuit provides
switched power when the
transmission is in P (Park) and
the engine is running. The circuit
is at 0 volts when the
transmission is in any other
position, i.e., R (Reverse),
N (Neutral), D (Drive) or
M (Manual). Note that the circuit
is also at 12 volts with the
transmission in P (Park) and the
ignition in LOCK/OFF. To avoid
the possibility of undesired
parasitic electrical load with the
ignition in LOCK/OFF it is
suggested that the Park/Signal
circuit be isolated by routing it
through the normally open
contact of a customer furnished
ignition controlled relay.
.A dark green/white, 0.5 mm²
(20 gauge) Vehicle Speed Signal
(VSS) provides 4,000 pulses
per mile.*These two circuits share a 15 amp
fuse. (10 amp combined
maximum load)

Exterior Lamp
Emergency Flashing
System - SEO 6J7
SEO 6J7 provides a high-beam
headlamps flashing module, rear
lamps flashing and control wire for a
customer-furnished switch to turn
the module on or off. The flasher
control wire is coiled under the
center of the instrument panel. This
control lead may be combined with
the interior wiring leads for SEO 6J3
when that option is ordered with
SEO 6J7.The headlamps flashing module is
located below the passenger side
front headlamp and forward of the
passenger side front wheel. The
module is connected to an inline
connector in the forward lamp
harness. The headlamps flashing
module is activated by the
application of 12 volts to a dark
green/red wire coiled in the
passenger side footwell. When
activated, the driver and passenger
side high-beam headlamps and the
high-beam instrument panel cluster
light will flash alternately at
2.4 flashes per second.
When the headlamps flashing
module is turned on, the module
sends a signal to the Body Control
Module (BCM). The BCM alternately
flashes the stop lamps and backup
lamps. Depressing the brake pedal
will override the stop lamp flashing
and placing the transmission in
reverse will override the backup
lamp flashing.Activation of the headlamp and
rearlamp flashing can be separated.

During daylight conditions, the
Daytime Running Lamps (DRL) are
automatically turned off whenever
the headlamps flasher module is
activated. During nighttime
conditions, the low-beam
headlamps turn on automatically
while the high-beam headlamps
flash. Turning on the high-beam
headlamps manually with the turn
signal/multifunction lever will
override the flashing module and
the high-beam headlamps will
operate continuously.
