Factory Fog Light Switch

[RustysBronco]

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

*sob*

I took you guys as the experts! Especially with someone already hacking the end off their "G harness" and mailing it to you guys. These should help jog the memory.

You should see our warehouse sometimes. We have "Adam Shelves" and "Adam benches" which is full of stuff i've hoarded over the years. Wiring harnesses galore, lights, rack accessories, rubber isolation boots, more brackets, more harnesses, more lights, nuts and bolts beyond belief. It's a complete mess of stuff

Extra points if you're organizing them in old baby food jars. That's a dad hack right up there with hoarding stuff for the "you might need later" moments.

So yeah that pigtail you sent me is probably SOMEWHERE burried in here. This is just 2 of a few spots my "projects" land on. ONE day I swear I will go through it all.

But we DO keep hardware pretty organized. Here is our hardware cart which we use for all of our KR Off-Road kits. Everything is color coordinated (there are cheat sheets on the bottom shelf you can see) and we also list the quantity and part # from our suppliers. So the stuff we sell is organized but when it comes to my R&D stuff... YEAHHHHHHH that's all over the place

If I had to organize that, I'd just set it on fire!

I would recommend cutting the G harness connector off and using some DT connectors and get the crimp tool, not the premade pigtails, we aren’t hobos here, we’re buying euro marker harnesses and rigging up auxiliary lights.

I only needed the power wire, not the ground, to trigger the Diode Dynamics C1R reverse light upfitter switch circuit since it already has a ground on that harness and by my basic engineering circuits knowledge told me “a grounds a ground!”

I have a 2024 2Dr manual Badlands with the Mid Package
I couldn’t find any connectors in the modular bumper
I also don’t see any parking sensors although the truck beeps when closing in on something front and rear
This photo is of the male connector from above the front right wheel well
After reading this long thread I believe my options are

1: Add pins to this connector and opening the loom
2: Wire the lights to my auxiliary switches.

My hope is to independently control the 3 lights separately
a fog light, an off road spot light and on road driving light to help spot deer

I would appreciate any guidance and opinions

@Ducati1098, I ended up with a M2DZ-11654-JC switch. I'm hoping that is just the latest revision of the M2DZ-11654-DC switch....or did I get the wrong dang thing for a '24 WT w/ LUX?

Looks like -JC is for use with a rear fog, but it only has the single switch in the center. I'm hoping that will still work with the rear fog disabled in FORscan.

-DC would be the correct one.
I’m not sure if -JC will work or not. I’d guess probably not, but I guess you’ll see.

-JC and -DC are identical all except:
DC is for front fog lights only (no rear)
JC is for rear fog lights only (no front)

Doh! Son of a gun!

If anyone is interest I posted a thread that details my install and wiring of factory fogs to a Big Bend without a C192 connector.

Since it appears that 25’s no longer come with the fog light harness in the bumper, is there any other solution out there to use the fog light switch?

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

Have to call in the part gurus then!

Wow, that was a long read with a lot of information. Thank you everyone for the details and options in here. That took some time to go through

I didn't realize that the '25s didn't have the pigtails for the fogs on the modular bumpers before I started down this path and already have my switch, and lights kit and the pigtail adapters from 4x4TruckLEDs for the mod bumper.

Has anyone been able to figure out the part number of the bumper harness for a modular bumper that would still have pigtails?

In the research I have done, I have found that the harness for a '22/'23 with the modular bumper with the front sensors would be M2DZ-15K867-H. I would have figured that would be the one with the fog pigtails still on it that I could get. The gotcha with this though, is that when I run my VIN for a '25 Badlands Sasquatch with modular bumper and high/lux, it returns the same part number.

I would prefer to swap out my bumper harness so everything is "factory" and plug and play rather thank taking apart connectors and adding pins and making my own harness, or tapping/cutting wires for my own harness.

As such, does anyone know what the proper harness would be to replace the bumper harness with that would then have the fog pigtails?

Are the Ford Parts versions (replacement ones) for the M2DZ-15K867-H still coming with the fog pigtails on them? I have tried reaching out to multiple dealerships/parts departments, and no one has been able to help or confirm for me.

I had looked on the Ford Canada parts site before for the -H variant of the harness and didn't find any, but I hadn't looked at all of the dealerships in my area. Decided to look again and found that one of them had one, so went to look at it before purchasing and it still had the fog pigtails on it. Looking at the label on it, it was manufactured in late 2023, so got one.

For anyone looking at this in the future, still don't know at this point if the newly manufactured harnesses still have the pigtails or not.

Now I just need a dry to tackle this project, or at least not the downpours we get in Vancouver.

Close it back up

Don’t forget to reinsert the retainer clip! I almost forgot…

Can you please clarify a few things....? This 'wrong pin' you mention...this is for your custom pigtail? The 5X terminal pack from Ford are the right pins for the body connector?

This is the body side of the connector? The 3rd pin hole doesn't exist and needs to be drilled? I assume the copper of the female socket is fully intact behind this, so extra care needs to be taken?

And this is the bumper side of the connector? Basically just insert the new pin pigtail to this and solder it to the rear fog light?

Thanks for the help!
