Fog lights stopped working need wiring diagram

SOURCE: 1996 jeep cherokee sport.

If it's a lighted switch, you should have 3 terminal connections on it. One for the "ignition on" wire (from your fuse box). One going to the fog lights to turn them on when you flip the switch and one ground for the switch light to work. If your switch doesn't light, you should only have 2 terminal connections (no ground).

Find an "ignition on" plug on your fuse panel. It is only hot when you turn your ignition to the on position (not crank position). With your keys out, it should not have any power to it. Hook your "hot" wire from fuse panel to switch, take your keys out of the ignition first to be safe. Now hook the other wire from the switch to the "hot" on your fog lights. You will have to find a pass through rubber grommet on your firewall to go through. Use a clothes hanger to help fish it through. Now ground your fog lights to a grounding screw somewhere in the engine bay. There should be a few you can use, possibly one of the bolts that hold the front shroud on. Make sure it's a metal surface and use sandpaper to scrape off paint to get a metal to metal contact. Cover area with petrolium jelly to ward off rust. If your switch is lighted, hook to ground wire on fuse panel. Test with ignition on. If it doesn't come on, check your grounds again.

Fog lamps are installed on the front bumper. The switch is located to the left of the steering column on the dash panel. The fog lamps are turned off by the circuit relay when the high beam driving lamps are turned on. The circuit relay is located on the right front wheelhouse panel near the blower motor.

Good luck, and remember rated this help.

   1. Distance between the light beam centers should be equal to the distance between the lamp assemblies on the bumper.
   2. Height of the light beams on the wall should be 4 inches less than the center of the lamp assemblies when mounted on the bumper.
      
3. Install all previously removed items after turning OFF the fog lamps.
