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.
