Special Equipment Options
connected to the electrical system
with a prefuse assembly (5). Also
included is an isolation relay (4)
which is activated whenever the
ignition is in the ON/RUN position.
The isolation relay is intended to
isolate the auxiliary battery and
connected load from the primary
battery to avoid unintended rundown
of the primary battery. When the
engine is running, the auxiliary
battery is charged. See Wiring
Provisions for 12-Volt Battery Power
Supply on page 15-3.

Exterior Lamp
Emergency Flashing
System - SEO 6J7
This feature provides a flashing
module, headlamp alternate
high-beam flashing, rear alternate
flashing of the stop and back-up
lamps, and a green control wire for
a customer-furnished switch to turn
the module on or off. A second blue/
green wire permits optional separate
control of headlamp flashing and
rear lamps flashing with a
customer-furnished switch.
To operate the rear lamps flashing
separately, 12 volt power to the
green wire must be OFF. Open the
blue/green wire at the flasher
module connector P181, terminal F
and apply a separate ground to the
blue/green wire via customer
switching in the 16 cavity up-fitter
connector, located at the equipment
mounting plate between the front
seats. Do not apply 12 volts to the
blue/green wire to avoid damage to
the BCM.
The headlamp flashing module is at
the rear edge of the passenger side
upper radiator support. When
activated, the high-beam headlamps
will flash alternately at 2.4 flashes
per second.
During daylight conditions, the
Daytime Running Lamps (DRL) are
automatically turned off whenever
the headlamp flashing 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 lever will override the flashing
module and the high-beam
headlamps will operate
continuously.
