Main Relay (Computer/Fuel System): Description and Operation

The Main Relay (also referred to as Fuel Injection Relay), located in a relay panel mounted forward of the left strut tower, supplies power to the ECU and a number of ECU controlled devices when the ignition is switched "ON", including the circuit opening relay, distributor, fuel injectors and a variety of solenoid valves.

The ECU energizes these devices when needed by completing the circuit to ground.
