Raptor Headlights on Lariat/Platinum?

[beaver24]

I have a 21 Lariat with adaptive LED headlights. I'd like to swap over to adaptive LED headlights from a Raptor for the amber DRLs. Has anyone else done Lariat adaptive to Raptor adaptive swap? I could only find folks on here that had the none adaptive quad headlights to start with.
Thanks for any info.

UPDATE:
Following this other thread I got them to work. Thanks to @Hawsa, @OleMustyBag , @JScaro, @PABamaFan and all the other folks in that thread.

For people with factory projector headlights, this thread is for you.
Our factory harness is a single 16-pin Molex MX150 connector, so it mates directly to the Raptor projector headlights. You will need to verify/change a couple settings in BCM with Forscan, thanks Hawsa. Make sure your DRL dim duty cycle is still set to the OEM 10% setting. If turned up at all, they will not flash with turn signal active. You will need to combine the turn signal wire into the DRL wire at each headlight. Using a diode on both turn and DRL to keep them from back-feeding in to one another is highly recommended. I'm not sure if the BCM has any protection internally from this already, but this has proven successful by several of us.
EDIT:More notes and a schematic on post #10 & #14.

You can order parts and make your own adapter harnesses or order a pre-made harness from a company like Starkey Products, Inc. example 1 & example 2. I purchased example 2 as it provides marker, drl, turn, and ground in a Deutsch connector for future lighting projects. Example 1 is cheaper if all you are doing is the turn & drl combine and they still give you marker lights branched out for future add-ons.

Digi-Key does not have minimum order quantities and has low USPS shipping cost. Order a few extra terminals in case you mess some up. Use thin jacketed 18awg & 14awg stranded automotive TXL wiring. The diode I used is a molded Deutsch 4-pin #DT04-4P-RT or #AT04-4P-RT01. You will need the mating male connector, female pins, and locking wedge.

If you want to make your own harness, these are the Molex parts-Digikey:
16-pin Male Connector #0334828601 (qty 2)
16-pin Female Connector #0334721601 (qty 2)

18awg Male Terminals #0330001002 (qty 16)
14awg Male Terminals #033000101 (qty 6)
18awg Female Terminals #0330123002 (qty 16)
14awg Female Terminals #0330123001 (qty 6)

Empty Orifice Plug #0343450001 (qty 16)

Set this to "0A"

You are a life saver! I just tried this swap yesterday thinking is was going to be easy. Change DRL with turn @ 726-38-02 and be done... Nope!

This is exactly what I was missing. The lights just weren't acting right and I had a suspicion that maybe a wire had to be either flip flopped or jumped.

Would you mind listing all the FORscan changes you made? I have a 402a 21 Tremor so I need to do exactly what you did. I'll even post a picture back on here once the project is done!

You'll want to follow this spreadsheet that Hawsa made. Most of mine were already set correctly on my Lariat. I'll go back and look at my change notes.

Yea I found that sheet too. That was the next thing I was going to try. Appreciate it sir!

In the end, for my Lariat, I think I only needed to change:
*726-38-02 xx01-xxxx-xxxx to set the DRL to dim with turn.
*Then ensure your DRL brightness for dim setting is at the factory 10%; 726-38-01 xxxx-0Axx-xxxx.
*Then doing the diode rewire of turn signal into DRL as mentioned above.

I'm going to attempt turning the led turn outage back on and see if that is still needed now that the turn wire is teed into the DRL wire.

I'm going to make my own harness, i already have a couple of these starkey harnesses in use and i don't want to interfere with what they're operating, since they're already tapping DRL, turn, and ground. I'll daisy chain after those harnesses.

So when the DRL is running, say at night with headlights on, does the DRL dim for the turn signal or does it still turn off entirely, or does it get brighter?

It dims to what your BCM 726-38-01 is set to. I will record at night, but from the driver's seat and watching the reflection on a car in front of me, it looks like it goes off. But the command is to dim. DRL dim is set to 10% duty cycle. When the turn signal hits, I'm not totally sure if the headlight has any fancy circuitry inside for this. It could be as simple as the DRL is being cycled 10%-100%-10%-100%, which is the flashing we see. Or the 10% is always active and the turn signal is nailing the DRL to full brightness on and off.

You can not have the DRL dim setting turned up at all though. I tried even 25% setting and the DRL will not flash, at least not perceivably. Turning the value to 25%-100% all looked the same brightness with headlights on; full brightness lol. After the diode rewire, I left it on 25% and no turn signal flashing. Turned it back to 10%, turn signals now "flash".

 

[beaver24]

Verified that turning the front turn LED outage to OFF is still needed.

So you have the same adapter harnesses I have. It was easy to rewire those. Because the way Starkey crimps the turn together on the headlight side and where they splice into the DRL for their 6-pin Deutsch branch; just pull the turn from the oem harness side and then pull the DRL from the headlight side of the adapter. Then run a new wire from diode pack to each connector. It leaves Starkey functionality as-is, blocks back feeding of those to their 6-pin branch, and does our turn-drl combine without back feed. It's a lot less work and cleaner than a whole new pass-thru harness between oem and Starkey. Do what you feel is right for your setup though, I'm just giving my opinion.

Let me wrap my head around this. It would be nice to not buy anything else.

I write schematics for a living. If it helps, I can draw this up in Draftsight tomorrow at work in 3 minutes. I can help others too. My snip-it tool, mouse writing above isn't the best lol.

Hey I was digging it lol

@beo_tom
Sorry, I forgot to post this schematic the other day. I only show the effected wires, and not the pass-thru wires.

 

[Jmitchelltfo]

That looks great @beaver24 !

I love threads like this. I have always thought that amber DRL's (or user selectable possibly) would be look so much better on every F150, vs just on the raptor.
