Front Fog Lights

Fuse C11 applies voltage to the Fog Light Relay coil and contacts. When the Fog Lights Switch is turned on, the Fog Light Relay coil is grounded energizing the relay. With the relay energized, voltage from Fuse C11 is applied to the Fog Lights through the relay's closed contacts and CKT 34. The Fog Lights are grounded through CKT 650 and 750 at ground G100 and G101.

On vehicles equipped with Daytime Running Lights (T61) the Front Fog Lights will automatically be turned off whenever the headlights are turned on by either the Headlight Switch or the Twilight Sentinel/DRL Module. When either one of these conditions occurs, the ground applied to the Headlight Relay coil is simultaneously applied to the Fog Light Inhibit Relay's coil. The Fog Light Inhibit Relay energizes and opens its contacts. The inhibit relay's normally closed contacts allows voltage to be applied to the Fog Light Relay's coil. When the Fog Light Inhibit Relay is energized its contacts open causing the Fog Light Relay's coil circuit to be interrupted. The Fog Light Relay now de-energizes and turns off the Fog Lights.
