DESCRIPTION
When the ignition switch is turned on (IG), the battery voltage is applied to IGSW of the ECM. The output signal from the MREL terminal of the ECM causes a current to flow to the coil, closing the contacts of the engine room junction block (EFI relay) and supplying power to either terminal +B or +B2 of the ECM.
