Factory Fog Light Switch

[Ride Em Bronco]

Bought this vehicle used, so I dont have all the info needed to make this work. So I have a few questions that I hope some of you could answer. THe first owner installed some LED lights where the factory would go to AUX 1 and AUX 2 (white and orange). I can activate the fog lights via the headlight switch, but nothing happens. I do see the dash icon come on.
I have looked and looked for any type of connection under or around the tow hooks, since I have the modular bumper. I do not find anything.

I do see an unused connector located behind this area.

Looking up from below this, I see this. The black red yellow are for the new lights seen above, but there is an empty connector right by it. Its tucked up with no droop to move it around to take a picture of it clearly, but I wonder if this is my factory fog lamp harness.

Here is a picture of the colors of the wires leading into the harness if that helps.

Thanks for the advice.

I like how the dual fog lights have a sleeve that fits right into the modular bumper opening. Would you know who made or marketed these fog lights?

Alright, I removed the skid plate a few minutes ago and confirmed that there aren’t any loose or capped off pigtails for fog light wiring in my 2025. I do have the modular bumper with parking sensors, a la the Lux package.

Here are some photos from driver and passenger side showing the view from below with the skid plate out of the way.

The visible wire on the driver side that runs into the shroud for the intercooler appears to be for the ACC adaptive cruise control radar assembly.

Great photos they really show what is there and not there.
I also have no front wiring. So many changes from year to year it is hard to keep up.
Did you find an answer on how to wire led fog lights up to a factory fog switch?
Is there a wiring diagram for the 2025's yet?
Before the bronco I had an xterra and you could download from Nissan all the wiring diagrams. Does Ford have this information?
Using the search I keep finding stuff for older years that is not relevant to the newer broncos.
It looks like I am going down the same path you did just a month behind you.

Those look like the Raptor style fog lights that Mabett was selling, although other brands sell the same product from China. They are not SAE/DOT certified and it’s not clear how much light they actually output. They draw 12W per side, so I’m guessing maybe 800-1000 lumens depending on quality of the LEDs used and the optics?

There was a long thread on them when they came out that probably will help you:

I ended up wiring them all to aux switches for now. I have the Baja Designs SAE white fog, SAE amber fog, and S2 white combo driving lights and have them on aux switches 4, 5, and 6.

Depending on the rest of the wiring, you likely may be able to simply order a 21-24 bumper harness. It depends if they changed or removed the circuit from where the bumper harness plugs in to the front main harness

Was hoping this was the case. I might try and see if the connector that mates up to the bumper harness has some extra wires that don’t match up. If anyone else knows already please chime in!

I wanted to chime in here again, like I usually do, and offer some more guidance/help with folks. We've been getting a lot of customers ordering the WRONG harnesses.

So we make a few different pigtails. Plastic/Capable bumpers AND Modular Bumpers. You need to make sure you order the CORRECT HARNESS.

There IS a difference

PLASTIC/CAPABLE BUMPER TRUCKS
If the truck came with fogs from the factory, the connector is H11. We sell the following pigtails

CrystaLux WP 2-Pin to H11 Pigtail, Pair (2021+ Ford Bronco w/Plastic or Capable Bumper)
These are for lights that utilize a WP 2-Pin Connector (Baja Designs)

https://www.4x4truckleds.com/crysta...2021-ford-bronco-w-plastic-or-capable-bumper/

Diode Dynamics Deutsch DT Adapter Wires, H11/H8/H9/800/881 (Pair)
These are for Lights that utilize a DT 2-Pin connector (Diode Dynamics SS3 without backlighting)

https://www.4x4truckleds.com/diode-dynamics-deutsch-dt-adapter-wires-h11-h8-h9-800-881-pair/

Diode Dynamics Deutsch DT Adapter Wires w/Backlight Tap, H11/H8/H9/880/881 (Pair)
These are for lights that utilize a DT 4-Pin Connector (Diode Dynamics SSC1, SSC2 and SS3 with back lighting)

https://www.4x4truckleds.com/diode-...wires-w-backlight-tap-h11-h8-h9-880-881-pair/

NOW, with that out of the way... onto the topic at hand.

MODULAR BUMPERS
The factory pigtail will be under the tow hook. Remove the plastic shroud around the tow hook and look inside that opening, on the bottom. You'll see the connector taped in there. This has a DUMMY PLUG on it. Soo make sure you remove that dummy plug. Then you can utilize FORSCAN to enable the circuit AND buy the proper fog light switch (lots of info in here about that).

We offer a bunch of different pigtails for this as follows:

CrystaLux WP 2-Pin to MX150 Pigtail, Pair (2021+ Ford Bronco w/HD Modular Bumper)
These are for WP 2-Pin lights (like the Baja Designs)

https://www.4x4truckleds.com/crysta...il-pair-2021-ford-bronco-w-hd-modular-bumper/

CrystaLux DT 2-Pin to MX150 Pigtail, Pair (2021+ Ford Bronco w/HD Modular Bumper)
These will be for DT 2-Pin connector lights (such as the Diode Dynamics SS3 without back lighting)

https://www.4x4truckleds.com/crysta...il-pair-2021-ford-bronco-w-hd-modular-bumper/

CrystaLux DT 4-Pin to MX150 Pigtail, Pair (2021+ Ford Bronco w/HD Modular Bumper)
Finally these have a DT 4-pin connector (Diode Dynamics SSC1, SSC2 and SS3 with backlighting)

https://www.4x4truckleds.com/crysta...il-pair-2021-ford-bronco-w-hd-modular-bumper/

If you have the DT 4-pin pigtails, you'll have a control wire hanging off the harness. This is for the back-light. Many of our customers simply tap this wire onto their man fog light harness (as they usually get a triple fog light kit from us). This way you don't have to run any wires anywhere. Tap the purple wire on the pigtail onto the backlight control wire on the triple fog light harness from us.

ONE IMPORTANT NOTE
If your truck came with a plastic/capable bumper and you decide to upgrade to a Modular bumper DO NOT buy the "Modular" pigtails. YES, we know you now have a modular bumper but your factory wiring is that of a plastic/capable bumper.

Also. IF you upgrade to a modular from a plastic/capable MAKE SURE you take your wiring harness OFF your old bumper and transfer it to your NEW bumper. That's VERY important.

Many customers don't realize you'll need to keep your factory harness which is ATTACHED to the bumper. There is a connector on the driver side underneath the headlight that is plugs into.

So keep that in mind. Just because you upgraded to a modular bumper does NOT mean you buy "pigtails" for a modular bumper... because you still have a plastic/capable bumper wiring harness.

All them harnesses, but not a single one for the trailing lights.

What’s a trailing light?

Rear fog lights, discussed a while back on the thread.

So to confirm, no one's figured out which connectors (either from Mouser, molex, etc.) works with the G harness, correct? I'm not interested in hacking into it.

Wow, no need to be rude.

Wow, no need to be rude.

It's been discussed all throughout the thread. @4x4TruckLEDs.com you guys even looked into it at point. So forgive me for being frustrated with re-answering questions already covered.

Now... in your defense, you did say there needs to be a front and rear thread.

No it's too late. You hurt my feelings

I'll be over here in my little dark corner crying because I didn't know what a "G" Harness was
