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.

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.

Infotainment section of the
owner manual for more

Wiring Provisions Front
Speakers - SEO WX7
About 165 cm (65 in) of auxiliary
speaker wire is run from the
instrument panel radio connector
and is coiled under the center of the
instrument panel. The wiring permits
the connection of front speakers to
customer-installed communication
equipment.Radio outputs from the front
speakers are sent to the rear
speakers to maintain the required
open door/key in the ignition
reminder chime
Electrical Connections
1. Disconnect the negative (−)
battery cable at the battery.
2. Remove the tape from the wire coiled under the instrument
panel to uncoil it.
3. Using proper electrical connectors, connect the
wires for the left front audio
output of the customer-installed
communication device. The left
front positive wire is tan and the
left front negative wire is gray.
4. Using proper electrical connectors, connect the
wires for the right front audio
output of the customer-installed
communication device. The right
front positive wire is light green
and the right front negative wire is dark green. The electrical
impedance of each speaker
installed is 10 ohms.
Notice: Overloading the vehicle's
electrical system may damage
your vehicle's accessories.
Do not overload the vehicle's
system by having unnecessary
accessories on at the same time.
5. The ignition must be turned off and the vehicle must be vacated
prior to attaching the cable to the
battery. Connect the negative (−)
battery cable to the battery and
tighten the bolt to 5 N·m
(3.7 lb ft).
6. Set the time on the clock and radio pushbuttons as needed.
