high current drivers, has the same termination point
as circuit Z11. The termination point is the left side
of the radiator closure panel.
If the system loses ground for the ganged circuits,
at the left side of the radiator closure panel, the vehi-
cle will not operate. Check the connection at the
ganged ground circuit eyelet.
SIGNAL GROUND

tected by a 20 amp fuse located in the PDC.
The Powertrain Control Module (PCM) controls the
ground path for the coil side of the relay on circuit
K51. This circuit connects to cavity 67 of the PCM.
When the PCM supplies the ground path on circuit
K51 the contacts in the relay CLOSE connecting cir-
cuits A14 and A142. The A142 circuit is spliced and
supplies power to the generator, fuel injectors, PCM,
ignition coil, and heated oxygen sensors.
HELPFUL INFORMATION

Center (PDC) and connects to battery voltage. The
contact side of the fuel pump relay connects circuit
A14 and circuit A141. A 20 amp fuse in the PDC pro-
tects circuits A14 and A142.
Circuit A141 supplies voltage for the fuel pump
motor. Circuit Z1 provides ground for the fuel pump
motor. The grounding point for circuit Z1 is the right
rear wheel house.
Circuit F12 supplies voltage to the coil side of the
fuel pump relay. The Powertrain Control Module
(PCM) controls the ground path circuit for the coil
side of the fuel pump relay on circuit K31. Circuit
K31 connects to cavity 74 of the PCM.
HELPFUL INFORMATION
Circuit F12 originates in the fuse block where it
connects to a bus bar fed by circuit A21. In the
START and RUN position, the ignition switch con-
nects circuit A1 from the PDC to circuit A21. A 30
amp fuse in the PDC protects circuits A1 and A21.
Circuit F12 splices to feed the ABS control module,
EGR solenoid, Torque Converter Clutch (TCC) sole-
noid, leak detection pump, and the EVAP/Purge sole-
noid.
Circuit F12 also connects to a bus bar in the PDC.
The bus bar supplies voltage to the coil side of radi-
ator fan relay and A/C clutch relay, as well as the
fuel pump relay.
VEHICLE SPEED SENSOR
Circuit K7 supplies 8 volts from the Powertrain
Control Module (PCM) to the Vehicle Speed Sensor
(VSS). The K7 circuit connects to cavity 44 of the
PCM connector.
Circuit G7 from the VSS provides an input signal
to the PCM. The G7 circuit connects to cavity 66 of
the PCM connector.
The PCM provides ground for the VSS signal (cir-
cuit G7) through circuit K4. Circuit K4 connects to
cavity 43 of the PCM connector.
HELPFUL INFORMATION
Circuit G7 splices to the speedometer and odome-
ter in the instrument cluster.

A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.
LOW FUEL DETECT INPUT
Circuit G4 provides an input to the Powertrain Con-
trol Module (PCM) indicating fuel tank level. This cir-
cuit connects to cavity 23 of the PCM connector.
The G4 circuit is also used for the fuel gauge
located in the instrument cluster. For operation of
the fuel gauge, refer to section 8W-40.
PARK/NEUTRAL POSITION SWITCH INPUT (3±SPD
TRANSMISSION)
On vehicles equipped with the 3±spd automatic
transmission the park/neutral switch provides an
input to the Powertrain Control Module (PCM).
When CLOSED, the park/neutral position switch
provides a ground path on circuit T41 for the coil
side of the engine starter motor relay. The case
grounded switch provides ground for circuit T41.
Circuit A41 from the ignition switch provides bat-
tery voltage to the coil side of the relay.
Circuit T41 splices to cavity 76 of the PCM. The
park/neutral position switch provides an input to the
Powertrain Control Module (PCM).
HELPFUL INFORMATION
In the START position, the ignition switch connects
circuit A1 from the Power Distribution Center (PDC)
to circuit A41. A 30 amp fuse protects circuits A1 and
A41.
