Circuit/System Description

The EFI relay and the ignition 2 relay provides ignition positive voltage to the control module and other engine control components anytime the ignition is ON. One side of the coil of the relay is always grounded. When voltage is applied to the other side of the coil, the relay coil is energized creating a magnetic field that closes the switch side of the relay. The switch side of the relay receives power from the applicable fuse protected positive voltage circuit.

Both the EFI relay and the ignition 2 relay are an integral part of the multifunction alarm module located in the fuse block - underhood. The circuit protection fuses for both relays are also a part of the multifunction alarm module.
