With Daytime Running Lights

CIRCUIT OPERATION
System voltage is applied at all times to the terminal 2 contact of the (Fog Lamp) Relay. System voltage is also applied to the coil of the (Fog Lamp) Relay whenever the LIGHT SWITCH is in the HEAD position. When the FOG LAMP SWITCH is pressed to ON, a ground is provided to the coil of the (Fog Lamp) Relay. This ground is provided at G201 through the LO contacts of the Dimmer/Passing Switch. With both voltage and ground provided, the (Fog Lamp) Relay is energized, its terminal 2-4 contacts close, and voltage is applied to the FOG LAMPS. Because the FOG LAMPS are permanently grounded at G102 and G103, they operate as soon as voltage is applied.

Voltage to the (Fog Lamp) Relay is only available with the LIGHT SWITCH in the HEAD position, and a ground is only available with the Dimmer/Passing Switch in the LO position. Due to this configuration, FOG LAMP operation is possible only in conjunction with LOW-BEAM HEADLAMP operation. The FOG LAMP SWITCH has its own illumination and an integral LED indicator that lights whenever the FOG LAMPS are lit.
