Driving Information
Vehicle Load Limits
The information in this section of the
supplement is for those who intend
to install additional equipment to the
police vehicle after it has left the
factory, and for those who will be
driving and loading the vehicle with
passengers and/or cargo.
Two labels on your vehicle show
how much weight it was designed to
carry, the Tire and Loading
Information label and the
Certification/Tire label. These labels
are attached to your vehicle and
give you the maximum load
capacity, the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for your
vehicle. See“Vehicle Load Limits” in
the owner manual Index for
additional loading information. The following guidelines can help
you with proper loading and load
distribution when installing
additional equipment on the
Tahoe Police Package.
{WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.

15-6 Special Equipment Options
The vehicle is equipped with wiring
provisions for a 12-volt battery
power supply. Refer to the following
information when adding electrical
accessories that will use the 12-volt
power supply feeds connected to
the vehicle's electrical system. The
wiring harness is located below the
instrument panel near the center of
the vehicle. The following
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.
The windshield wiper switch and
the radio must be turned off
before attaching cables to the
battery.

15-8 Special Equipment Options
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) Servicing Relays and Fuses

The following information tells how
to access the vehicle's relay and
breaker center for checking and
replacing breakers.
The breaker and relay center is
located behind and above the
instrument panel storage
compartment. Remove contents
from the storage tray. Using the tab
at the back of the compartment,
drop the tray down gently toward
the floor. It will hang from the hinge.
The breaker/relay center is located
above the right rear corner of the
storage compartment. The bracket
is attached to the instrument panel
structure with two screws.
Replace a 30 amp circuit breaker
with GM Part No. 12182117 circuit
breaker, or equivalent. Replace a
relay with a GM Part No. 12193604

relay, or equivalent. Replace a
50 amp circuit breaker with a GM
Part No. 15319848 circuit breaker,
or equivalent.
Reinstall the storage tray into the
compartment by lifting it into the
instrument panel.
Auxiliary Battery Power
Junction Blocks
Two auxiliary power junction blocks
are located within the driver side
rear cargo area jack stowage
compartment. Each junction block is
powered directly from the battery
through a 50 amp circuit breaker for
connection to customer‐furnished
equipment. The two circuit breakers
are located in the breaker/relay
panel forward of the instrument
panel glove box. A maximum load of
50 amps (600 watts) can be
connected to each junction block.
The wiring diagram for this circuit is
shown as part of the diagram for
“Wiring Provisions–12 Volt Battery
Power”. The two junction blocks are
connected to coiled 1.5 m (5 ft)
branches of the rear body harness
and fastened near the jack.
Mounting of the junction blocks can
be at customer‐selected rear cargo
area locations permitted by the
branch harness length and using
customer‐furnished mounting
hardware.
The junction blocks should not be
attached to the interior trim plastic
components without appropriate
backing hardware to the mounting
bolts.
To connect the customer-furnished
equipment at the junction blocks,
use the following steps:
1. Disconnect the negative (−)
battery cable.
2. Connect the customer-furnished equipment positive leads to the
junction block terminals and
tighten to 15 N·m (11 lb ft).
The ignition must be turned off
and the vehicle vacated prior to
connecting the negative (−)
battery cable to the battery.
3. Reconnect the negative (−) battery cable to the battery.
Torque the bolt to 5 Y
(3.6 lb ft).
4. Set the time on the clock and radio pushbuttons as needed.
See “Introduction” in the
Infotainment section of the
owner manual for more
information.

15-16 Special Equipment Options
5. As one person watches the roofhole from the outside for the end
of the harness, a second person
from the inside of the vehicle
should snake the harness
toward the hole.
6. Pull out the wiring harness being careful to avoid scraping the
insulation on the edge of
the hole.
7. Extend the wiring harness to the accessory.
8. Connect the dark green wire to the accessory hot terminal.
9. Connect the black wire to the accessory ground terminal.
10. Cover the hole in the roof with a durable sealant such as
silicone rubber sealer.
11. Reinstall the overhead console access panel/lamp lenses. Option B: Use Wiring Harness
Package 12150250. Obtain from
GM Service Parts through the
GM Dealership
1. Drill a 32 mm (1.25 in) hole in
the outer roof panel in the area
shown in the illustration. The
hole should only go through the
outer panel. Remove all sharp
edges from the drilled hole.
2. Remove the inside overhead console access panel/lamp
lenses.
3. The accessory harness is coil tied to the passenger side of the
vehicle at the console inner
bracket.
4. Cut the tape holding the harness coil.
5. As one person watches the roof hole from the outside for the end
of the harness, a second person
from the inside of the vehicle
should snake the harness
toward the hole. 6. Pull out the wiring harness being
careful to avoid scraping the
insulation on the edge of
the hole.
7. Cut the wire to length. Install terminals to wire ends and insert
into the connector. The dark
green wire goes to cavity A and
the black wire in cavity B. Push
in the secondary lock to retain
the wires.
8. Attach the harness assembly from the package to the
accessory. Cover with the
supplied conduit for added
protection. Connect the orange
wire to the accessory hot
terminal and the black wire to
the ground.
9. Complete the connection from the roof harness to the extension
harness. Cover the mated
connector with the supplied
foam. Push the foam covered
connection and excess wire
through the roof panel hole.
