19. WATER PUMP WIRING
A.1 Escalade/Denali/SS: Mount the supplied
water pump relay on the fire wall located to
the right of the FMU bracket. (See Fig. 19-a.)
A.2 H2 Hummer: Mount the supplied water pump
relay on the lower plastic area of the power
distribution block next to the fuel pump relay.
(See Fig. 11-f.)
B. Connect the red 12-gauge wire from terminal
#30 to the supplied fuse holder using the sup-
plied butt connector. Install a ring terminal on
the other end of the fuse holder. (See Fig.
19-b.)
C. Feed the yellow wire from relay terminal #85
to the fuse box (electrical center) on the driv-
er’s side of the engine bay. Route the wire to
the yellow wire from the fuel pump relay. Tap
into the line using the supplied “T” splice con-
nector. (See Fig. 19-b.) If the vehicle does not
require an inline fuel pump, route the wires
directly to the fuel pump relay. (See Fig.
19-c.)

(See Fig. 19-c.)
D. Run the black wire from terminal #86 on the
fuel pump relay to ground.
E.1 Escalade/Denali/SS: With the long red
12-gauge wire connected to the water pump
relay terminal #87, route the free end down
along the fenderwell and under the base of
the radiator over to the positive (blue/green)
wire on the water pump. Secure as necessary
to avoid heat and sharp edges.
E.2 H2 Hummer: With the long red 12-gauge
wire connected to the water pump relay ter-
minal #87, route the free end down the fend-
erwell to the positive (blue/green) wire on the
water pump. Secure as necessary to avoid
heat and sharp edges.
F. Run the negative (brown) wire from the water
pump to a clean ground.
G. With the key on, make sure the charge cooler
water pump is operating and that water is
flowing through the surge tank. Fill the surge
tank if necessary. If the water is not flowing,
remove the charge cooler supply hose and
lower until water flows out of the hose. If nec-
essary, provide light suction to the hose to
help prime the pump. Verify water flow. Do
not let the pump run for extended periods (30
seconds or more) without water flow. Fill the
charge cooler tank until the level stabilizes.
