Fog/Driving Lamp: Description and Operation

^ Set the lighting switch to the "HEAD" position.

^ If the fog light switch is set at the "ON" position when the dimmer switch is at the "low" position, current flows through the multi-purpose fuse, lighting switch, fog light switch, fog light relay, dimmer switch, daytime running light relay 1* and ground, causing the fog light relay contacts to close.
NOTE:
* indicates vehicles with daytime running light.

^ Once the fog light relay contacts have closed, current flows through the dedicated fuse, fog light relay (contacts), fog lights, and ground, causing the fog lights to go on.
