I’ve heard a lot of people call the non-premium/non-projector reflector headlights as quad headlights but whatever the case, I’m talking about the regular halogen reflector headlights.

The trucks with the Quads (or reflector type) headlights do not have the dedicated DRL wires up to the headlights. The SLT platform and above should have the Dedicated DRL wires at the plug under the fuse box. That where I added the pigtails to add the Dedicated DRL wires.
There's an option for "Dedicated" that is a separate wire which allows a drop out option that turns off when the turn signals are activated.
That’s kinda what I figured being that on those trucks, the default DRLs is the highbeams at a lower intensity, right?
Actually all modes of designated DRLs work with the DRL dropout feature.
There have been a few people report the high and low beams DRLs stop working when used with the drop out option.
Not sure if it's a default but that's usually what I see around here and on Canadian trucks that venture over to Detroit. I think the reduced intensity is about 6 or 7 volts
Really? Hmm.... I dont know why they would unless something happened when re-designating the lighting for the DRL's but then again, I haven't tried using my high beams or low beams as DRL's so I wouldn't know. I have tried my fog lights as DRL's and I know for a fact the DRL dropout still works when those are selected.
From what it sounds like to me being that the trucks with the premium projectors have the dedicated DRL wires and the trucks with the regular quad-halogen headlights dont, even for the Canadian trucks, the trucks with premium projectors are default turn signals for DRL's and probably for the trucks with the regular halogens, its the high beams at a lower intensity.
I'm relaying what other people have reported when enabling the high or low beams as DRLs along with using the drop out option. The factory highs or lows don't use the drop out option.
You’d think they would because the whole purpose of the DRL dropout is so that when you have your DRL’s activated, you’d want the high beam or low beam DRL on that side to go out so that they’re not hindering the visibility of the turn signal on that side but who knows. Like I said, I’ve never selected my highs or lows as DRL’s so I have no idea.
I’m 100% certain- at least on my truck anyways and it’s a 2018 that on the factory projector headlights, the dedicated DRL wire is most certainly used because like in my truck, whether I select “dedicated” or “turn signal” for designated DRL‘s, I will get the same exact result that makes my front amber LED strips as the DRLs. I’ve tried it both ways and even before I got Alfa when I had the dealer activate my DRLs, it showed on Alfa that “dedicated” was selected.
Hmm, news to me. I just told the guy who was asking about all this to just figure out what wire in his new aftermarket headlights goes to the white DRLs and then just run those wires to the ignition coil circuit in his fuse box using a fuse tap which would give him the desired results being that he may not even have those dedicated DRL wires anywhere.
The really low trim level tricks may not have them, but bighorn/slt trucks and up should. Like I said, you need to pull the fuse box, find the harness, and re-pin the connector to add the wiring, but it's not hard and gives you full control of the drl settings, either via Alfaobd or through the 8.4.
