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, 20 gauge (0.5 mm²) circuit, Hot in
ACCESSORY, RUN or RAP (Retained Accessory
Power).
.
A pink, 20 gauge (0.5 mm²) circuit, Hot in START
and RUN. (7A maximum load)
.
*A yellow/black, 20 gauge (0.5 mm²) transmission
park signal. This circuit provides switched power
when the transmission is in P (Park) and the
engine is running. 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, 20 gauge (0.5 mm²) Vehicle
Speed Signal (VSS) provides 4,000 pulses
per mile.
*These two circuits share a 15 amp fuse.
(10 amp combined maximum load)
