Fog Light Relay Conversion (so you can run your highbeams & fog lights at the same time)

I found this on another website and thought it might be usefull to some people. I did it this morning and it took all of 2 minutes. Except I didnt bend the contact I just put a peice of plastic over it.


This 6-step writeup has been performed on a 2001, a 2002, 2003, and a 2004 TJ and has worked properly on all 4 year models.

Legal Notice: in some states (it may be a Federal law?) having high-beams and foglights concurrently operating is for off-road use only and may also be illegal. However, if you don't leave both high-beams and foglights to blind oncoming traffic, you should be fine. It is my belief that this decision should be left up to me and not decided for me by the manufacturer and/or government.

If you have the factory fog lights in your TJ, you may have noticed that they will only work if your headlights are in low-beam only. To test this, while parked facing a wall at night, turn on your low-beams and your fog lights. Now switch to your high-beams. Your fog lights turned off didn't they? Well, there are situations I have run into in which I needed both high-beam and my fog lights and I couldn't do that due to this factory-flawed "bonus feature."

This is probably the easiest and least expensive mod there could possibly be for your Jeep. This entire project took only two minutes (this estimate includes opening/closing the hood), and this requires only a pair of pliers to complete the job (although you might even be able to do it with your fingers!).

* Open the hood
* Locate the main fuse box (passenger side, just forward of the battery)
* Open main fuse box
* Pull the fog light relay (the diagram in the fuse box lid should have it listed)
* While looking at the 5 pins of the relay, bend ONLY the pin as shown as the upper left pin (Pin #1 in the FSM) in the photo below. Leave the other four pins alone.
* Put the relay back in place and close up the fuse box, YOU'RE DONE!

Tim, I did mine a couple of months ago. Works fine. I don't use my high beams very often anyway.

Nice write up ... :drive:
I'll have to try it one my 95 XJ to see if it will fix mine also....
Worth the price of a relay to get both working....
Oh and it's a fine to run with the high beams on anyway...
With oncoming traffic.... So if you dimm your light as you are supose to
then theres no ticket, as the fog lights will come on anyway....

Thanks for the info...
