At last I think I can help all of the 2001 X owners who don't like the way their factory fog lights work. You can have the option of running the fog lights anytime OR only when the parking lights are on.

First the disclaimers-
1) I have a 2000 X so I haven't tried this. I do believe that it will work correctly.
2) The modification will involve cutting into the factory wiring harness. If this bothers you DON'T DO IT.

You will need:
1 butt splice, 18-22AWG, typically red, Radio Shack #64-3108 or equivalent.
1 "tap" connector, 14-18AWG, typically blue, Radio Shack #64-3052 or equivalent.
1 6" piece of 18AWG stranded wire, color matched to your X
electrical tape

The first step is to remove the 5 philips head screws from the bottom of the steering column cover. The two halves will snap apart and the top half can be removed. There are 3 connectors for the turn signal/headlight/foglight switch. We're interested in the one with 2 wires and the one with 8 wires.

On the 2-wire connector harness, cut back the tubing to reveal a couple inches of the wires. They are red/black and red/something else. Cut the red/black wire leaving both ends long enough to work on. Tape up the end that is still connected to the truck harness.
Using the butt splice connect one end of the 6" jumper wire to the stub of red/black wire at the 2-wire connector.

Here is where you need to choose how you want your lights to operate:

For those that want the ability to turn on the fog lights anytime, connect the 6" jumper wire to the purple wire in the 8-pin connector harness using the tap connector. Note that the headlight warning system will NOT remind you to turn the fogs off if you choose this option.

For those that want the ability to use the fog lights whenever the parking lights are on, connect the 6" jumper wire to the blue/red wire in the 8-pin connector harness using the tap connector. In this case the headlight warning system will let you know if you leave the fogs on.

Test it.

Reassemble the column covers.

All Done.

I hope some brave soul will try this and let us all know how it works.
