WIRING PROCEDURE
Wiring the pump to an oil pressure switch provides power
only when the ignition switch is on and the engine is
running. This prevents the pump from running if your
engine stalls. Use 12 gauge wire or larger and be sure to
disconnect the battery ground cable before wiring the
pump. Refer to Figure 4 when connecting the pump to
an oil pressure switch.
The pump may be wired directly to the ignition switch "ON"
terminal and grounded to the frame or battery. Refer to
Figure 5 when connecting the pump to the ignition switch
"ON" terminal.
