Connected my Oracle Fogs this morning, using the DT 2-pin to MX150 pigtails.
So easy! Saved me having to do any splicing/soldering.
Few minutes with Forscan, and I'm all set.

I just noticed today that my fog light switch does not turn on the fogs when the headlight dial is set to "Auto". Anyone else experiencing this after connecting and making the Forscan changes? The factory fog light button will work when the headlight dial is in any other position except "Auto"

If the headlights are not actually on when they’re in auto (not dark out) you won’t be able to turn on the fog lights by hitting the button.

I just did the changes, some how only the passenger side fog is turning on. Any idea what I’m missing? I’m using 4x4 new pigtail which isn’t the problem as I just switched between sides and tested both. Neither is the actual fog. It seems I’m not getting power to the driver fog oem plug.

This may sound silly but did you enable the drivers side? They each have to be enabled individually.

May not be silly at all, in which of the steps should I a had done it.

The step where you enabled the RF (passenger) fog light.

The step where you enabled the RF (passenger) fog light.

i don’t recall 1 step where it noted RF, the steps I follow were these
BdyCM Configuration
Front fog lamps - change this to "Enabled".
Fog Lamp Switch - change this to "Enabled"
Using Front Fog With High Beam - "Allowed"
IPC
Front fog lamps - change this to "Enabled"
BdyCM (As-Built Configuration)
726-42-01-xxxx-xxxx-xxxx - Change this to 726-42-01-xxxx-0101-xxxx

I rechecked and everything was as updated. I am definitely not getting power there. could I have a bad factory plug?

Apologies, it wasn’t specified since it didn’t really need to be. It would be

726-42-01-xxxx-0101-xxxx

The first 01 is the Left (Driver) and the second is the Right (Passenger). If you double check that it’s enabled then yes it could be a faulty plug or a problematic pin in the main harness. You’d need to diagnose with a multimeter to see if you receive anything at all and depending on your skill set you could check continuity through the harness to verify it’s the harness or something else.

Not sure if it was the factory plug or my wiring of the pins (I got a good crimp on it, so subscribing to theory it was the factory plug), but the passenger side didn’t light up. I didn’t test but just cut off the factory plug, wired direct, and poof, they worked, so for me it wasn’t a harness issue.

It looks like the harness for the fog lights has been eliminated on 2022 Job2 builds-I can’t find it behind plastic covers and looking under and behind the bumper I don’t see anything.

I have a Big Bend Mid package with the modular bumper.

This is a Job 2 build? What’s the build date?

Looks like I can see the push pin the plug is mounted to on the bottom left of the crack/opening but not for sure.

Willing to bet it’s in there. Just a little difficult to find. I doubt they made a new separate harness

I recall reading somewhere on these forums that it was restricted to high and lux package builds.

Good catch yes I completely missed thinking about that specification. The vehicle has to have to have the front parking sensors
