Moving Fog Lights off Fog Switch and Related Forscan Changes

[hamster]

On the 2024, you have one of the OEM bumper lights wired to the fog switch and the other wired to Aux 1. You can use wiring harnesses from John @Specialtyperformanceparts to easily combine both bumper lights to the fog switch and reuse Aux 1 up top.

I wanted to run just the outside fog light in amber with the DRL using Auto light switch position. You can use Forscan to make that change and I ran it for a few days. The problem is that the fog does not come on when the headlights are on as the DRL circuit is off. And when it is daytime and running DRL, you can't turn off the fog if need to. I really liked having ability to turn my fogs on / off under any circumstances via Aux switches on previous Raptors.

I really prefer BD lights over Rigid (just a personal preference) and I wanted to upgrade to non-SAE lights and move them to Aux switches. So talked to John and he adjusted one of his kits to get me the right connectors / harnesses with the BD lights and brackets. Sure made the install easier!!

Now I have the Factory Amber bumper pair on Aux 3, the other white bumper light pair on Aux 4. With the cable harnesses from John, I also moved Aux 1 and Fog connection back up top for future use. I have plans for Aux 1 and Aux 2, but the Fog connection is just moved because that is how the wiring worked out and I can now easily return to OEM functionality when I sell the truck by simply switching a few connections in the engine bay.

I can now turn on one or both of the bumper light pairs depending on what I need at the time.....but....did not like having the OEM fog connection hot in case I accidently hit the fog switch. Also, if you do hit the fog switch it will throw a couple of DTC because the truck sees an open circuit. Took me a little bit to figure out the Forscan changes to disable the OEM fog switch and now everything works like I want it and no open circuits. Here are the ForScan changes in case anyone needs them.

Great job on this BTW!

We have received a few inquiries on which harnesses he used, so I thought I would share that with everyone for simplicity.

This is the relocation harness. It plugs into ONE or BOTH the Fog and Aux 1 Switch connections on each side, and runs up to the switch wire area. So it "Relocates" those connections so you get your Aux 1 BACK up there with your other 5 switch wires and your Fog Switch wire as well. This way you can connect anything to any of them that you want.

This small harness lets you take back your switch wires! If you purchased an 801A Raptor with the factory Fog Lights, your Aux 1 wire and the fog switch wire are stuck, relocated down to the bumper. This makes it difficult to connect them to other harnesses, such as our triple harness. Or maybe...

Here is a video-

These are the OEM Fog Splitters.

These splitters can plug into either the connectors on each side for the Aux 1 or the Fog switch.

2 Molex Connector Splitter MAIN APPLICATION/DESCRIPTION- If you have an F-150 or Bronco in the Raptor trim. These splitters allow you to combine BOTH of the OEM Ford/Rigid fogs together to either the fog switch or aux 1 switch. This frees up the other. We recommend our switch wire relocation...

So running down the scenarios.

In his case, he had the relocation harness and only connected the side for the Aux 1 and then ran it up to the switch wire area so now he has all 6 switch wires.
Then, he took the 2 splitters and connected them to both FOG switch connectors in the bumper. Splitting that connection to BOTH lights on each side.
Of course followed by the reprogram.

That is one option.

Some, just get the splitters and put both pairs on the Aux 1 and don't use the fog switch. Thats another option.

Others just get the relocation harness and bring both connections up to the switch wires, and use it to connect other harnesses or lights in that or aftermarket bumpers.

You guys make this too easy John! Thank you for the detailed response, I'm ordering the fog switch relocation harness now. I'd like my OEM fog sets wired to separate AUX switches, not both on/off at the same time. SPV comes through again!

John - I purchased the aux 1 relocation Harness from Sidney and the whole kit for the 3 rigid radiance fog lights ( one SAE pair and 2 rigid radiance scenes) my plan is to move aux 1 back up to my upfitter. Use Aux 2 for my A pillar LP4s (Baja designs) and then run my sae off of aux 4 and my 2 rigid radiance pairs off of aux 3. I haven’t wired it yet just put the lights together, now I am wondering how I am going to get power for them to run on day time running ? My goal was the have the background amber be on for my new triple fog kit and LP4s while ignition was running. Can you clarify what is needed in order for them to run on daytime running?
I asked Sidney to give me everything u would need for the same setup you have in the following video

I’m basically trying to achieve what you have here except my LP4 are on my pillar.

So in those videos with our Marker adapter, they run with the parking/running lights. Not the daytime running lights or when the ignition is on.
You can in forscan turn that circuit to be on with the ignition. I know several people that did do that. However, you can also simply turn the headlight dial to parking lights any time and use them on demand.

There are some valid arguments to using them all the time. The main one is just like anything. LED’s have a life. So running them constantly will shorten theirs and usually they get more dim rather than just burn out completely like an old bulb.
Since in the daylight, sun blazing. You don’t see them really all that well as being on. It might be considered wasteful. But with the marker adapter, they come on at dusk, with the marker lights and any time with the headlights and are fully integrated and automatic.
