With Daytime Running Lamps

Voltage is supplied to the Fog Lamp Relay at all times through the LT BLU (316) wire and the Fog Lamps Fuse. When the Fog Lamp Switch is ON. voltage is supplied to the coil of the Fog Lamp Relay through the YEL (317) wire. Ground for the relay is provided through the Daytime Running Lamps Module and the DK GRN (1317) wire. With the relay energized, voltage is provided to the indicator lamp through the PPL (34) wire and the Fog Lamps through the PPL (34) wire and the PPL/WHT (134) wires. Ground for the Fog Lamps are provided through the BLK (154) wires and ground G154.

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