I apologize for the original confusion. I went and checked some As-Builts and by default it was LIN from Base to First Edition so I never thought to include that as a needed change.
No apology necessary. That you for all the leg work you’ve done.

Looking to install the Baja Designs Foglight kit on my Bronco when it arrives. Trying not to take up three upfitter switches so my plan is to use one upfitter for the two smaller pods on each side and then using a factory fog light switch for the Amber fogs. Since my truck will have the modular bumper I know I’ll have to swap in the switch but was curious to feedback. Couldn’t I wire that switch directly to the battery with a fuse and use an inline relay to control it via a trigger from the fog light switch. I would just have to figure how to get the foglight switch power if it doesn’t from the factory harness. Thanks!
Best way to figure this is to go to an OEM Ford Parts supplier and start slumming through the parts list. There is a switch part, probably with a wiring harness to match, that will support all the fancy things. Then you just need a few pages from the shop manual.

The forum members have an open action item to see if anyone can find the rear fog pigtail in the rear harness. ANYONE FIND IT YET? smile
This reminded me I wanted to check for this. I did some peaking and didn't see it so I went and looked at wiring info. It doesn't exist unfortunately. However it's not completely non-existent. The harness it would be included in is actually for the license plate light. The connector (attached below) is pre wired for the rear fog on the body (female) side. So if you do want to use this as a source for some rear lights you would just need to land a wire into pin 3 on the bumper (male) side of that connector, enable rear fog in FORScan and voila you have an easily toggled rear lighting solution.

I wish I would have dug into this sooner for those who were eager enough to actually buy the rear fog switch, the idea definitely isn't dead but it is just a little bit of extra work than anticipated. Honestly though I feel like this is still a relatively easy way of adding light power since you don't have to do wiring all the way back to a power source under the hood/use the upfitter provisions. Hope this helps someone and I hope to see something come of this finally. With this discovery I myself am kind of intrigued to go through this process. I don't have any rush to add rear lights but it's crossed my mind for an option in the future.

Just an update from a Black Diamond - that wire/harness is NOT in the front bumper. So, likely everyone with a 2022 will be better off…as of now it looks like the wiring is at the switch and potentially goes to C203. From there - we’ll have to see. Thanks to @flip for helping me sort this out. Bummed it’s not going to be as easy as I hoped to upgrade the headlight switch and save an AUX.

Stinks, but that's workable. Anyone know a p/n for a terminated lead for this that I can then splice into a homemade fog harness?

Wow! , you’re awesome! My Bronco is currently scheduled for build “week of Jan 3. “ When it get’s here , I’ll make up the third conductor for the male side to add it for an “upgraded “ rear light feature. I’ll probably use it for a rear SS1 Clear lens fog with red LED back light . Is the running light pin ieither pin 2 or pin 5 by any chance. It will save me looking manually. Smile

My add on harness will need 2 conductors plus a ground . Thanks for making this very doable . While the switch assembly is still on back order, it will eventually fill. While I wait, I’m trying to work around it by utilizing @BeeBops accidentally getting an incorrect version.
I have ordered the wrong dual fog deliberately to see if I can utilize it. IE modify to utilize parts from both.
…..will advise as I do not have an ETA.
I’ll call the parts folks today to see IF it was in stock?
Thank you again!!!!!! 🎂 appreciate it!

Alfie,
The fog light indicator is on your instrument panel and the images on the switch do NOT illuminate ,
Regards,
George
I assume you mean the switch doesn't change illumination to show its on? I'm going to also assume it's backlit like all the other interior buttons...?

I’m in the same boat.

C203. I highlighted the two cavities the wires should be in.

Correct, the switch face doesn’t illuminate when it’s on and the switch isn’t backlit

So there's actually 3 separate connectors the wiring passes through. The one you show is actually the middle of them. A faster way to check if they're landed (forgive me if you already did) is to look for connecter C192 or looking at the BCM (fuse panel). If they're not landed in C203 you're going to have to run wires all the way from the BCM harness (C2280G). I don't have access to a Black Diamond or other trim to see if they used a one size fits all harness and C192 is still spliced into the main harness and is prewired but capped off since it just does fogs and parking sensors. If so then you're golden. If not then like I said you will have to hope it's at least in C203.

Definitely pop the panel down below the steering column and look at the BCM. The top right plug right above all the fuses is where these wires land. You should see a yellow/orange and brown wire just like mine. If you don't see this you will have some extra work to do for sure. I'm very hopeful these are landed, go through C203, and go right to an unused C192.

I've attached pictures below. The one looking like I was upside down to take is where C192. Forgive my partial blocking of it, I used it to piggy back some other wiring. For reference it's on the drivers side right below the headlight. But if the harness is completely different then this wouldn't be spliced in at all. I hope this leads to something positive for those without High/Lux options. Hell if it's still there that means everyone gets it.

The positive is 2 and the negative is 5.

@D2dhanover where are you getting all the wiring diagrams? Do you have a service subscription? Helm hasn't released the wiring manual yet, they state it will be available 12/31/21
