The 12volt 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 12 gauge (3.0 mm²) 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 20 gauge (0.5 mm²) blunt
cut, light or dark blue control lead included in the 4 foot
(122 cm) 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, 10gauge
wires (5.0 mm²) 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 4 foot (122 cm) of coiled wires can be
accessed by removing the cup holder on the top of the
trim panel. The third 10gauge (5 mm²) wire is a blunt
cut lead which is part of the 4 foot (122 cm) loop of wire
coiled under the instrument panel near the center of the
vehicle.
An 8gauge (8 mm²) 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 4 feet
(122 cm) long.
