What exactly does the main relay power?

G'day all.

Just rewiring my engine bay and don't THINK I need the main relay.

I am not longer using the stock ECU at all.

Does it only power the ECU, or does it power other things such as the wiper motor and the like?

The main relay feeds only EFI-related components (injectors, coils, solenoids, sensors and the ECU).
