I got the single.

BD Pocket Lights are installed and the fogs are working off of the factory wiring. I still need to connect the driving and cornering lights to the upfitter switches. That will have to wait until it warms up some

Here are some Pics. I modified the 4X4Truckled.com upfitter harness removing one circuit and use that connector to make a harness to connect to the factory foglight switch
I ran the Wiring harness along the hood release cable.

Then Tied in to switch 3 for the Driving lights and Switch 4 for the cornering lights

Here is the finished product. I didn't think i would like the Bezelless look, but it is growing on me.

Foglights

Driving lights

Cornering lights

All Lights

I still need to aim them.

So, do you just swap out the mirror light buttons off your original switch...?

All of you Black Diamond owners who are wanting to do this, can't we buy a Big Bend front bumper harness? They have fog lights but no sensors???

M2DZ wait too long - I used ML3Z and did a pop and swap with the mirror lights and the tank opener switch. Reprogrammed on ForScan and all works perfect.

What did you have to change in forscan?

Set fog lights on - see the post from D2dhanover in this thread - very thorough explanation.

I've been trying to find time to tackle this for everyone and finally did. I hope this can serve as the base of a write up for everyone, I don't have much experience making write ups but I will try my best.


To enable and utilize the factory fog light harness these are the steps needed. You will need ForScan (obviously but had to clarify) and the headlight switch of your choice, mine specifically is the auto lamp one with spot light buttons and just the single fog light in the center of the dial (I forget the part number if anyone knows)

Connect to the vehicle and go into configurations --> BdyCM and open it.
You will want to find and change the following:

Front fog lamps - change this from "Disabled" to "Enabled".
Fog Lamp Switch - change this to "Enabled"
Using Front Fog With High Beam - This is an optional change but if you want to use fogs with high beams change it to "Allowed"

Write the settings made, you are finished with the BdyCM for now

Next you need to open the IPC which will turn on the fog light indicator in your gauge screen:

Front fog lamps - change this to "Enabled"

Write this setting and now we will go onto the As-Built change.

You will need to open BdyCM (As-Built Configuration). BACK UP THIS FILE in case anything goes wrong you can restore the original.

Locate the following line:

726-42-01-xxxx-xxxx-xxxx (My Badlands specifically was 726-42-01-0000-0000-0575)

You will need to change the second box to 0101. ForScan does autochecksum calculations so what I ended up with was 726-42-01-0000-0101-0577

Write this change


I originally started with just the first two parts but while the indicator would show up on the dash I was not getting power to the fog light harness in the bumper. I was curious and compared to a 2021 F-150 spreadsheet. This 726-42-01 is the control line for what the Left and Right fog light circuit actually does. There's a few options but the default setting is "not used". The setting I changed it to (01) is "Fog cornering" (I assume 04 for Fog Only will work too) but there is another one (05) which basically turns that circuit into an always on 12v. The switch does not turn it off and while I tested it with the vehicle on I forgot to check it with the vehicle keyed off though I assume it would be a key on only setting. I mention this just because it could be useful to somone here who may not be hooking up fog lights but might want a low amp, I believe the fuse is only 5 amps, source for other accessories.

For those curious here is the full list of options but I only tried the two I mentioned:

LF_Fog_Lamp_Ckt_Usage_Cfg: 00=Not Used 01=Fog Cornering 02=Fog DRL 03=Fog DRL Cornering 04=Fog Only 05=Power Supply



Also, I did not research or attempt anything relating to the Rear Fog Lamps. I know some people here are seeking that but unfortunately I didn't dive into that yet.
