WATER PUMP WIRING

WATER PUMP WIRING

Mount the supplied water pump relay in the
same location as the fuel pump relay. (See
Fig. 11-a.)

Connect the red 12 gauge wire from termi-
nal #30 to the supplied fuse holder using the
supplied butt connector. Install a yellow ring
terminal on the other end of the fuse holder
and bolt to the fuse box power supply. (See
Fig 11-a.)

Feed the yellow wire from the relay terminal
#85 into the fuse box. Route the wire to the
yellow wire from the fuel pump relay. Tap
into the line using the supplied “T” splice
connector. (See Fig. 11-a.)

Run the black wire from terminal #86 on the
fuel pump relay to ground.

With the long red 12 gauge wire connected
to water pump relay #87, route the free end
down along the fender well and under the
base of the radiator over to the positive
(blue/green) wire on the water pump and
connect the two wires. Secure as necessary
to avoid heat and sharp edges.

Run the negative brown wire from the water
pump to a clean ground.
