information describes the breaker
and relay location and provides a
wiring diagram to aid in connecting
customer equipment.
Electrical Connections
Notice:Before modifying or
adding any wiring, be sure that it
will work properly with your
vehicle's wiring system. Because
there are so many modifications
that can be made for many
different bodies and accessories,
GM cannot take responsibility for
any changes made. Such
changes may not be covered by
your GM Warranty. Have the work
done by an experienced electrical
technician. All wiring must be properly
protected by fuses, etc. and must
be routed properly so that it will
not be cut, pinched or rubbed by
other parts of the vehicle. Do not
route wiring in areas where it will
be very hot. Be sure not to
overload the vehicle's wiring,
connectors and components. All
added wire must be at least the
same size as the wire being
attached to for proper fuse
protection.
Installation Instructions
–12‐Volt
Accessory Power Supply
1. Disconnect the negative (−)
battery cable at the battery. The
negative (−) battery cable must
be disconnected before the
positive wiring lead is connected
to the power accessory.
2. Locate the power supply harnesses, one under the
instrument panel near the center
of the vehicle, and one within the
driver side rear cargo area jack
stowage compartment. 3. Prepare the wires that are to be
used to connect the power
accessory. Do not remove the
unused wires. Tape unused
wires back in their original
position under the instrument
panel.
4. Complete the wiring installation of the customer added
accessory with additional wire
required for the specific
electrical accessory power
connection. The wire gauge,
3.0 mm² (12 gauge), should be
the same as the wiring of the
installed harness.
5. The ignition must be turned to OFF prior to attaching the cables
to the battery, or serious damage
to the Body Control Module
(BCM) may result.

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. 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.
Call Kerr Industries at 905‐725‐6561
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.
