Battery power is supplied through two fusible links, one 50-amp and one
65-amp, to three circuit breakers and two control relays located in the
control center above the accelerator pedal. A 50-amp circuit breaker feeds
power directly from the 50-amp fusible link through a 10 gauge blunt cut
wire. Two 30-amp circuit breakers supply power from the 65-amp fusible
link through the contacts of the control relays to 12 gauge blunt cut wires.
The blunt cut leads are part of a 5 foot coil on the floor under the
instrument panel.
Each relay is to be operated by a 18 gauge control lead included in the 5
foot coil under the instrument panel. A 8 gauge system ground lead is also
provided in the 5 foot coil.
The total current available through the 12 volt power supply is 110 amps.
Two blunt cut wires provide ignition controlled power; one is hot when the
ignition is in Accessory and On; the second is hot when the ignition is in
START and ON.
A third blunt cut wire from the body control module provides a Park-
Enable signal. When the transmission is in P
ARK zero volts (not ground)
are present and 12 volts are present when the transmission is in any other
position. The circuit to operate a single customer-furnished relay.
A fourth blunt cut wire provides the Vehicle Speed Signal (VSS).
AUXILIARY POWER OUTLET-100-AMP
An auxiliar
y ba
ttery power junction block is mounted in the trunk on the
right side support strut rearward of the wheelhouse. The auxiliary
junction block has a split buss with two terminals which are electrically
separated. Two 50-amp fusible links at the battery protect the junction
block 8 gauge body wiring. Maximum combined capacity of the two
circuits is 100 amps.

This feature provides a 10mm ground stud located in the trunk on the
right side just above the red Trunk Auxiliary Battery Power Junction
Block. A 10mm flanged hex nut grounds the 10mm stud bolt to the
vehicle and is torqued to 26 lb-ft (35N-M). A plain 10 mm hex nut is
provided for customer ground termination. Recommended torque for this
second nut is 7 lb-ft (10N-M) plus or minus 1 lb-ft (2N-M).
