Factory fog light switch conversion (multi switch to dash toggle)

This sounds like a plan. I do know that fogs must shut off with high beams in Commiefornia at least. Or at least that used to be the case - dunno about other states, etc...
So after a day of research (weather has been too crappy to be outside) it looks like the fogs simply run through a switch in the MFS with heavy contacts but a poorly designed support post that melts when the contacts get hot from the current draw. In the diagram, the relay is simply the high beam switch that turns the fogs off when the high beams are turned on.
So in the end I think I'm going to put a relay between 13/14 and call it good - that should get everything going again.
And yes, Calif. has an excess of stupid laws... lots of them are either unenforceable, or our friends in blue simply don't want to become fog light police! And trust me, with the new $0 bail law here that's putting us all in danger, they have much more important fish to fry!

Looked in the California vehicle code about fogs on with high beams... couldn't find anything prohibiting that combination other than a discussion about how high beams are useless in dense fog... a no brainer as far as I'm concerned.

Finished my conversion successfully yesterday... will be posting soon on how and what I did.

Sorry everyone for the delay, had a family emergency that kept me off the net for almost a month!I
Can't add too awfully much except to say that the fog light circuit is basically a stand alone and is not connected to anything else inside the MFS. if you remove the two wires from the MFS plug harness and run them through a dash switch via a relay, you should be good to go! just make sure you check everything with a multimeter of some other test equipment to make sure you have the right wires before you start cutting and you should be good.
in my case, I always leave a small pigtail when cutting wires "just in case"! ...saves a lot of headaches!

also, if your one of those that want to run your fogs with the high beams on like I do, the quick and simple solution is to remove the relay in the fuse box under the hood, and simply use a jumper in the socket. Quick and simple! No wire cutting, no long and difficult instructions!
just use fairly heavy wire to handle the load and good quality (not harbor freight) crimp on spade lugs.
have fun!
 
here's a pic of the jumper i put in my jeep...

HA! You're right where I'm at at this VERY moment! I'm just about to splice into the two wires, I came in to remind myself where the dimmable dash lite wire is. However, I'm getting power through to the relay, but the fogs themselves aren't working, neither one. I'm going to get the switch installed, then troubleshoot the why of the lites themselves. Not looking forward to unplugging their harness - if there's one thing on this jeep that I've come to loathe, its the connectors! Ridiculously difficult to unplug, even after you have the ridiculously difficult "latch" moved to the correct location.
 
This is my plan B - tap at the factory fog lite relay under the hood.

Hey Zorba - Any chance you did this fog light mod? My MFS blew again, seems to blow every 4 years, so now I want to just bypass the MFS to turn on/off the fog lights.

Curious if you did it and what parts you used?

I tapped into the two wires going to the MFS, and ran them to a toggle switch on my center console. Blow-by-blow here:

I later added a relay so the fogs would turn off with the key. Then even later, I added another switch for a rear fog lite.

Nice ornament hanging from the rear view mirror, Turkish/Egyptian????
 
In the end I pulled the high beam cutout relay out of the fuse box and jumped the appropriate connection with a short peice of 12ga and two spade crimp connectors so when the fogs are on, they're on regardless of high beam status.
I live in the country and the fog light police look the other way! 😄
That being said, doing it this way allows reinstalling the relay a snap if the need should ever arise!
 
I eventually installed a set of "off road floods" purchased from somebody here. I wired a relay connected to the 4WD sense switch so when in 2WD, the stock fogs come one, when in 4WD, the "off road" lites come on. The stock fogs still switch off with high beams, but the off road lites do not.
 
So I’ve ran an entirely new circuit for my fog lights and installed a switch in the dash panel. I’d like to have the instrument panel fog light activate when I flip the switch. I thought by tapping into the white/orange wire on the MFS that would do the trick. However, the white/orange wire has 12v constant. Which wire should I look for to activate the fog instrument light? ‘06 Sport. Thanks!

There may be other WT/OR wires on the mfs, but you need to find the one that goes to the cluster (C1 pin 4).
