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."  These devices include the circuit opening relay, distributor, fuel injectors
and a variety of solenoid valves.  The ECU completes the circuit by grounding these devices when indicated by its calculations.
