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 wir-
ing the pump. Refer to Figure 3 when connecting the
pump to an oil pressure switch.
