Adding fog lights to a 2003 forester X

Hope this helps!

The Easiest Way is to Get the Wiring Harness Diagram with the Colors and Verify that you plugged the Fog Lights into the Correct Harness. I once had a FORD that had a Fuse BOX that had a FOG LIGHT and No Power to that Fuse.

Make sure you test the Fuse at the Box and then Trace the wires and if the Switch was wired at the Factory, you should be all set

I WOULD WIRE IT SEPERATLY!!

Front Fog Light Assembly

REMOVAL

1. Disconnect the ground cable from battery.

1. Remove the two clips and lower mudguard on side that bulb is being changed.
2. Disconnect the harness connector from bulb on back of fog lamp.

Front Fog Light Bulb

REMOVAL


1. Locate back cover on fog lamp assembly where bulb is located inside.

1. Remove the back cover.

1. Remove the spring retainer, and then detach the fog light bulb.
2. DO NOT TOUCH HALOGEN BULB!! Oils from skin will cause bulb to explode during operation.
   

This is the diagram for the fog lamps ( headlamp is a different cell ).
If you are trying to add them to the existing wiring, do not expect the headlamp switch to cab fuse panel wiring to be there ( that is usually what is missing when you can find the fog lamp connectors under the front of the truck ).

File Save as so you can magnify it with the JPEG viewer you use.

You really should never touch the wiring harness on todays cars. Aftermarket electronics can not be trusted. If you want to install lights make your own circuit completely seperate from the factory wiring

Have you looked down under the front bumper area where the fog lights would be located on this vehicle?

DRL function is built into the body control module. If your car doesn't have DRL, you'll need to do a full reprogramming on the BCM. Not feasible. Plus, adding HID to halogen headlight assembly is a horrible idea and *******.

im pretty sure these cars were already prewired for fog lights .there should be some plugs behind the bumper to fit them.if not get back i will explain how to wire them up.best of luck.

Answer is on Bavarian Auto web site:
3 Series 92 to 98 Fog Light Replacement-
To install a fog light, insert a flat blade screwdriver through the front bumper grill and release the fog light retaining clip. Remove the fog light and disconnect the wiring harness. Installation is the reverse of removal.
