A. Locate the supplied 14GA red wire and
wire loom. Route the wire from the water
pump over to the power distribution box on
the driver’s side. Use the supplied loom and
tie-wraps to secure the wire.
B. Use the supplied slide connectors to attach
the red wire to the (blue/green) positive
wire on the water pump.
C. Connect the brown wire to a good ground
with the supplied black wire, ring terminal
and slide connectors.
D. Locate the positive wire running to the fuel
pump at the power distribution box. Use the
supplied T-tap terminal and male slide con-
nector to connect the water pump positive
wire to the fuel pump positive wire.
6. Water Pump Wiring
NOTE: In some cases, the water pump must be
primed on initial start-up. This may be
accomplished by turning on the pump,
removing the RETURN line from the
charge cooler and providing light suction
on the hose to remove air in the system.
E. Fill the system with 25% anti-freeze and
75% water. Cycle the key a few times to
verify water is flowing. Let the pump run for
a few minutes to allow for any trapped air
to be released. The combination of running
for short periods of time and stopping the
pump helps in purging the system. Top the
system off when all air is purged.
