Without Daytime Running Lamps

Voltage is supplied to the Fog Lamp Relay at all times through the LT BLU (316) wire and the FOG LAMP Fuse. When the Fog Lamp switch is ON, voltage is supplied to the coil of the Fog Lamp Relay through the PPL (34) wire. Ground for the coil is provided through the LH Headlamp GRN (11) wire, and the High beam element of the element of the LH Headlamp and the BLK (150) wire to ground G125. With the relay energized, voltage is provided to the indicator lamp and the Fog Lamps through the normally open contacts of the relay and the PPL/WHT (134) wires.

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