RELAYS

Operation
The relays, located under the hood, assist with component
operation like the fan, fuel pump, and rear differential.
The differential relay, controlled by the AWD switch and ECU,
operates the differential solenoid.
The fan relay, controlled by the ECU and Temp Sensor, operates
the fan.
The power relay, controlled by the ECU, turns on power for
components such as the fuel pump, injectors, etc.
