With Daytime Running Lamps

Voltage is supplied to the Fog Light Relay at all times through the LT BLU (316) wire and the PWR ACC circuit breaker. When the Fog Light Switch is ON, voltage is supplied to the coil of the fog light relay through the PPL (34) wire. Ground for the coil is provided through the Daytime Running Lights (DRL) Module LT GRN (911) wire and the LT GRN (11) wire, the High Beam element of the LH Headlight and the BLK (150) wire to ground G125. With the Fog Light relay energized, voltage is provided to the indicator light and the Fog Lights through the LT BLU (316) wire, the normally open contacts of the Fog Light relay and the PPL/WHT (134) wires.

If the Headlights are on HIGH BEAM, voltage is supplied to the LT GRN (11) wires and the HIGH BEAM elements of the headlights. This removes the ground for the Fog Light Relay and de-energizes the circuit.
