RELAYS
Operation
Located in the fuse box under the dash, the relays assist with
component operation like the fan, fuel pump, and EFI system.
The fan relay, controlled by the ECU and Temp Sensor, operates
the fan.
The EFI relay, controlled by the ECU, turns on power for
components such as the fuel pump, injectors, and ignition coils.
