WIRING PROCEDURE
Wiring a pump to an oil pressure switch will provide
power only when the ignition switch is on and the engine
is running. This will prevent 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 3 when connecting the pump
to an oil pressure switch.
The pump may also be wired directly to the ignition “ON” terminal and grounded
to the frame or battery. Refer to Figure 4 when connecting the pump to the
ignition switch “ON” terminal.
