Separate DRLs from turn signal lights

I have been poring over the electrical wiring diagram and trying to figure this one out, but I was wondering if anyone knows of a way to separate the signals for the DRL and the turn signal so that I can put different LED-style aftermarket DRL lights on and retain the factory turn signals.

Anybody know anything about this? I welcome alternate suggestions as well, although I'd REALLY like to get that effect the other more luxury vehicles have, where the DRL turns off to allow the turn signal to work only on the one side the turn signal is on.

Relatedly, I welcome suggestions for LED turn signal inserts (front and back) that work and don't hyperflash, and for, ideally, short (like maybe 8in or less) white LED DRL style lights i can maybe put in my grill.

Sorry, my subject matter got a little multifaceted here, but TIA!

I had actually found that excellent writeup before, which put me in mind of the possibility in general of splitting these signals. The thought of doing it the way you did interests me, somewhat, but as I mentioned, I'm hoping for more of a grill lighting, kind of like this, but you know, on a 4runner.

If nothing else pops up though, I'll probably end up doing your mod, or something like it.
Side note: I see at the bottom you mentioned there you got all your lighting from vleds. This includes the parking lights in the headlight assembly? and the fogs? What are you using from their site specifically for those, if you recall? I've had hit-and-miss (mostly miss) luck on the internet finding sufficiently high-lumen LED direct bulb replacements.

Did you ever find a solution to this? I am trying to do the exact same thing. I have a 2007 and just added some halos. I currently have them spliced to the green and white wire so the factory drl / turn signal and the halos are always on together. What I am trying to achieve is to have the factory bulb only hit with the turn signal is activated and off in normal drl mode. I havent been able to see anyone else do this.

Regrettably, I've sold my T4R to a friend (who has also since run it into the ground by towing excessively), and moved overseas, then back, then there again, to Thailand, and I never did figure this out before then.
As a side note, I've stayed in the Toyota family: I'm currently rocking arguably the de-facto standard in Toyota Trucks, the Hilux (2014 "Vigo Champ"). And of course, with light mods. Pics!

Anyway, sounds like you found one of those LED halo + light controllers that distinguishes between a constant voltage and an intermittent one (constant-on DRL vs turn/hazard flashing)?

If so, I wonder if it's possible to pull a wire off said controller to run your turn signal instead (typically they only flash the orange LEDs, and only solid-on white, so there's separate contacts coming off the controller for those two signals). I guess usually not though, since they're generally designed as one sealed waterproof system.

The other option I see (based on the 4th gen Electrical Wiring Diagram I still have in my files) for actually getting the proper signal is to pull it from the last point it's available. That is, you'd probably want to set up a relay+fuse for each turn signal light (might be able to work it back through the original fuse for each turn signal?), with a 12v constant on one side, and pull the ground from wires 7 (green-black stripe) and 8 (green-yellow stripe) off of the Turn Signal/DRL/Hazard relay "D2", which is up in the driver area, behind the driver's junction/fuse box. According to the EWD, these wires come straight from the stalk, which contacts ground when switched on for each side.
That does mean you'll have to route two lengthy wires through the firewall.

I do NOT recommend pulling power for the signals through those skinny control wires; it'd probably work, especially considering you probably replaced the incandescent bulbs with lower-power LEDs, but nonetheless it's just safer to use relays to electrically isolate high-power and low-power circuits.

If that doesn't work, I don't have an actual T4R to mess with to give better suggestions from, so.. sorry.

Ah, sorry, forgot about this thread for a few days.

I did try to upload my PDF copy of the wiring diagram but it's over the forum's file size limits.

However, I did find this link to the same EWD (with a bonus mechanical guide haphazardly spliced onto the end of it too, hence 500 pages as opposed to the original EWD's about 400).

http://docshare01.docshare.tips/files/25108/251083248.pdf

I suppose page 150 (according to the PDF file's page numbers, not the EWD's printed-on-page page numbers) is the start of some relevant information.
