Engine Idle Speed - Alternator
Output
Normal idle speed for the engine is
set for 600 rpm. To increase
alternator output while the
transmission remains in P (Park) or
N (Neutral), and the electrical load
on the alternator is large enough,
the engine idle speed can rise to as
high as 800 to 1000 rpm.

6. Reconnect the negative (−)battery cable to the battery.
Torque the bolt to 5 Y
(3.6 lb ft).
7. Reset the clock time and radio pushbuttons as desired.
The 12‐volt battery power is
supplied through two underhood
mega fuses, one 125 amp and one
60 amp. This underhood power is
fed to the breaker/relay center via a
harness that passes through the
driver side front of the dash, and
routes across the instrument panel
to a position forward of the glove
box. The breaker/relay center is
mounted to the instrument panel
structure forward of the glove box.
The center includes a plastic
bracket, two relays, two 30 amp
breakers and three 50 amp mega
circuit breakers.
Two 30 amp breakers supply power
from the underhood 60 amp mega
fuse through the contacts of the
control relays to 3.0 mm² (12 gauge)
blunt cut wires. These two blunt cut leads are part of wire coil under the
instrument panel near the center of
the vehicle.
Each relay is operated by a 0.5 mm²
(20 gauge) blunt cut, light or dark
blue control lead included in the
122 cm (4 ft) loop of wire coiled
under the instrument panel.
Three 50 amp mega circuit
breakers, protected by three fusible
links, supply power directly from the
underhood 125 amp mega fuse
through three, 5.0 mm² (10 gauge)
wires. Two of the wires are routed
through the body harness to buss
junction blocks in the left rear of the
cargo area and secured near the
jack and tools. This 122 cm (4 ft) of
coiled wires can be accessed by
removing the cup holder on the top
of the trim panel. The third 5 mm²
(10 gauge) wire is a blunt cut lead
which is part of the 122 cm (4 ft)
loop of wire coiled under the
instrument panel near the center of
the vehicle.
An 8 mm² (8 gauge) ground lead is
also provided, and it is located
under the front passenger sill plate.
It can be accessed by removing the
sill plate and pulling the loop of wire
at the front of the plate. The lead is
122 cm (4 ft) long.
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.

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
by opening the dark-blue/yellow
BCM circuit at the flasher module
connector, C122–F, and applying a
customer-switched ground to the
harness side of the wire in the
connector.
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.

Battery power is supplied through a
30 amp fuse to a wiring harness
located in the roof. Power is
controlled with a switch located in
the overhead console. The
customer or vehicle upfitter must
complete the installation to an
added accessory such as an
emergency beacon lamp.
Maximum rated electrical load is
21 amps (250 watts). The added
electrical requirements must not
exceed 21 amps (250 watts).
Running the accessory for long
periods of time with the engine off
may run the battery down.
Installation Instructions–
Emergency Vehicle Roof
Panel Lamp
Wiring to the accessory can be
done by either directly connecting
the wire in the roof to the accessory
(Option A) or by using Wiring Harness Package part number
12150250 obtained from GM
Service Parts (Option B).

Pulling the wiring
harness through a panel hole that
has sharp edges may cause
damage to the wire and/or wire
insulation. Remove sharp edges
from the panel hole before pulling
the wire through it.
Option A: Roof Wires Directly to
Accessory
1. Drill a 10 to 13 mm (3/8 in to 1/2 in) hole in the outer roof
