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.
