Factory Fog Light Switch

[FordOwner]

I enabled/allowed these three settings in Forscan:

IPC module- Rear Fog Light Indicator - changed from Disabled to Enabled
BdyCM module - Rear Fog Lamps - changed from Disabled to Enabled
BdyCM module - Using Rear Fog with Trailer - changed from Inhibited to Allowed

With those three Forscan changes in place my rear fogs will turn on with my headlights on and the rear fog indicator light will illuminate the dash.

This worked for me with the fog light lead wire connected to Pin 3 the CLS37 (WH-BU) wire. The White - Blue wire in the C424 connector. See posts from me on pg 70 and/or this awesome post from @Chritaka https://www.bronco6g.com/forum/threads/factory-fog-light-switch.22937/page-71#post-2015340

Hi
I’ve ordered the double fog light switch along with these rear lights from DD.
They will come on when in reverse but you can also tie them into a switch to have on when you want. Hoping there is a way to use the rear fog light switch and connector??
Thanks!

Do you have a link to these?

I swear I looked multiple times in this thread - can't find it...

is this the factory fog harness? Driver's side looking in ...

I have 3 rigid radiance scene in there. I just also bought this:

First up - wiring one set of the fogs on each side to the factory front fog switch.

so, locating the factory fog harness is going to be important. Thanks for any help!

No, that’s not it. Remove the plastic covers around the tow hook brackets and you’ll see the connectors.

No just remove the plastic shroud around your tow hook. Real easy. Then look on the bottom underneath the tow hook. You'll see the harness taped there.

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.

looking from the other angle -

I assume this is the fog light wiring?

@4x4TruckLEDs.com that's some great information, thank you!

I was wondering, do you sell pigtails that work with the Mabett fog lights? The examples you provided below did not mention those designs. Maybe it matches one of the connectors you mentioned and I'm just unaware? Thanks for the help!

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

All that's left is a harness for the rear bumper for rear fogs and the circle is complete.

…also remember, if you have the modular bumper w/o sensors you do not have the fog light wiring/harnesses and it dead ends above the fender where you’ll need to tap.

documenting in hopes it helps someone...

Yes. That’s the correct connector

 

[HPR23Wildling]

progress - but now stuck

New switch installed...check

buuuuuut - the connectors I was shipped for this job are not matching...

I have these:

https://specialtyperformanceparts.c...s-w-many-vehicles?_pos=1&_sid=05b7f4a8a&_ss=r

and the y harness:

Took out the blank placeholder and ends dont match.

I am stumped - what am I missing?
