The oil pressure switch supplies an additional path for current to flow to the fuel pump when oil pressure is above approximately 7psi. It will
not disable the fuel pump if the oil switch fails. The orange wire feeds both the oil pressure switch and the fuel pump relay. The red wire at the fuel pump relay goes through the relay and directly to the fuel pump ONLY when the relay is deactivated. The red wire is called "pump prime" and is used only for diagnostic purposes. The wire dead ends, usually within a few inches of the relay.
