Trying to improve this:
How to run your turn signal as a DRL together with the white LED DRL for TRD models
with Switchbacks.

For all SR/SR5 owners with those hideous factory halogen DRL/TurnSignal/Parking headlights, we've found the solution. I made a harness with the incredible help of @caribe makaira who knows A LOT about this stuff, and he guided me through the whole process and here are the results, steps, stuff you need to buy ETC.

The first thing you'll need is the harness that is sold online, afterwards go to CorsaTechnic and buy the following accessories
Make sure you have also a soldering gun, solder, heat gun, heat shrinks, pliers, wire cutters, nippers and crimping tool. Also you'll need two (2) resistors.

This is how you're going to be installing the new connectors.

Locate the two rear turn signal cables that are located in your fuse box. Keep in mind there's no need to cut your box because the new wires will follow the same route as those cables, (yellow wire is the driver's side and blue wire is the passenger's side rear signal)

Here's the location of each cable as stated above.

The factory connector where your parking/DRL/turn signal is you're going to create a bridge between ground and the far side (turn signal) wire, this will eliminate the hyber-blinking from the system on the front turn signals (the wire in the middle is going to be connected into the (four pin connector) that you're going to buy and will connect to the harness you bought. (this cable will power both your DRL's and your parking lights)

This is how your resistors will be connected.

This is the harness you'll need to buy, the two separate connectors go into the factory side-marker which are not going to be used.

Basically most of the stuff I used to build my own harness. (Didn't use add-a-fuse and other stuff I had there but I had it anyways just in case, you now have the advantage of not having the spend the extra $$$$ on stuff you won't use for this)

Cheap soldering gun and heat gun I got on Amazon, if you're like me don't use this much don't need to buy the most expensive equipment.

I learned how to connect these on youtube, its pretty simple, make sure you don't forget to put the rubber boot BEFORE soldering the terminal that goes into the connector.

Solder and heat shrink wire to wire connections.

After soldering the cables and installing the connectors you'll have some sort of additional harness.

This means, time to move on to the truck, disconnect the ground terminal of your battery.
Open the fuse box and disconnect the connector where the two rear turn signals are, this is going to help you spread them open more comfortably and to tap into them easier.

Run all the cables, make sure you install heat shields on the wires so that they're protected from the elements and of course the heat. Use metal zip ties to hold the resistors in place away from any plastics or wires, these thing get super hot +270 Deg F.

I ran the cable from the passenger side turn signal by removing the top plastic cover that's on top of the radiator, ran the cable underneath the metal and used the holes to zip tie the wire to the top so it is secured and away from the heat of the radiator.

To tap on the turn signals you can either use posi-taps, T-taps of just common wire taps, I used the last option because didn't have anything else available.

After doing this, don't connect the battery just yet. This is the most important step, REPLACE THE REAR TURN SIGNALS WITH LED BULBS, this will even out the circuit of the rear turn signal and you'll be able to run both front and rear turn signals off the same wires.

If you don't do this the system will overload and the turn signals will stop working because halogen bulbs draw too much power.

Once you've hooked everything up, use the heat protection to wrap both new turn signal wires, wrap with electric tape and hold in place next to the factory harnesses by using zip ties (make sure you don't over tight the zip ties) you want to give it a little wiggle room.

Make sure everything looks factory like it was factory installed.

Connect the ground terminal to the battery and try them on. Your DRL's and parking will light at the same time when you turn them on.

One thing is that the "DRL" in the switch will not do anything its one annoyance but it is what it is.

You'll be able to run your DRL's with the fog lights on. (I installed those LED's that switch color between 6000K and 3000K when you turn them on and off and it looks great)

The rest will work like factory.

FYI I removed that zip tie because it was too tight.

Secured the resistor in a safe place with a metal zip tie. (can be found on amazon)

I removed the plastic that's located there and secured the tubing where the turn signal cable goes to the passenger side and then reinstalled the plastic (it uses 8 plastic tabs)

Eureka moment for me, finally (after replacing the rear turn signals with LED bulbs) the front were also working. Also tried the emergency lights and of course the lock/unlock lights and they all work perfectly. The sequential turn looks awesome.

Here's with Fog lights and DRL's

DRL's with yellow fog lights

DRL's only.

I don't have more pictures for the turn signals, that would have to be a video which I did not record.

If you have any questions you can ask me or @caribe makaira for help. Thanks to him I got this wired and working, it was all his ideas and guidance.

Now ya'll SR/SR5 owners go put full LED's on your trucks!!! or not...

So I am new here. Looking to add those oem lights to my 2020 sr5. Just so I am clear. The only way to add them is with this harness and the modification you did above? They are not simply plug and play with the harness?

correct. SR5 does not have the LED lights so a different wiring harness. You would have to modify the harness to run the LED lights, or get aftermarket lights designed to be used on an SR5

I think alpha Rex makes a model for the SR5s, and Morimoto too. Not 100% sure just going off of memory. Quick google search will show you

Yea just bought the morimoto. Not sure why someone doesn't make the same harness morimoto does

If anyone is interested I'm selling my OEM headlights, the ones that came was with the truck, as well as the taillights. DM me.

I can ship at buyer's expense.

Posting here because its not letting me post in buy/sell.

Thanks.

Yup I bought the morimoto XBs

I’m the least tech-savvy person on these forums. Also, I am an SR5 owner who despises my headlights. I desperately want the LED upgrade.
However after reading these seven pages I have come to the conclusion that I will NOT make the upgrade. I wish someone would create a simple solution for those of us who don’t know anything about splicing, tapping, or whatever.
Alpha Rex are hot garbage, and Morimotos need an extra harness for the SR5s (not mentioned in the instructions or online anywhere).
Anyone upgrade to the Morimotos on their SR5 and everything work properly? I checked the XB thread, and SR5 owners expressed frustration.

Which generation Morimotos did you get?
Do they work as advertised?
Did you need any extra parts?

No the morimoto Xbs are truly plug and play. Sickest headlights out there. A++++ Get them quick.

@Puppypunter made a plug & play harness for OEM led headlights on the SR/SR5. You could reach out to him and see if he’d be willing to make another one.

Jonny50604 · Feb 4, 2021

No extra harness needed with xb

Puppypunter · Feb 4, 2021

I did make a harness for the SR/SR5. Totally plug and play. There is a small bug I am working out with a hyper flash under certain conditions, but I am confident I will get that corrected. Should have more on that in a week or so (just waiting for a few things to come in, then off to @Gtboosted for final testing). When I’m happy that all of the bugs are worked out, I will probably whip up a few for sale, as well as post a DIY thread for anyone that wants to tackle it themselves. It’s that damn turn/DRL being combined that messes with this so bad. My end goal for a harness will be true plug-and-play, in the sense that you unplug the old headlight (which I’m sure you are already doing as they are getting removed), plug my harness into the now open connectors, and plug the other end of my harness into the headlight. So @DawgLover and people like him can have the option of the OEM LEDs too, not just those TRD guys

Looking forward to the new and improved harness and final results from @Gtboosted . If everything works out then I might take a stab at those OEM lights.
I saw on another thread that people suggested turning off the DRL option on their Entertainment screen. That seemed to solve a lot of problems. Maybe that helps?

It would help to turn it off, but if you wanted DRLs you would have to substitute another signal. You could do something like ACC so the DRLs are on whenever the truck is or something like that? But what I want is something that just does what I set the switch to do. Nice and simple. Plus, I think disabling the DRLs is only an SR5 option, so still not a solution for us lowly SR peasants

So happy with the first prototype harness and the headlights! All is working fine but just a minor thing. Turn signal hypeflashes when all lights are off.

BUT I didnt buy these expensive headlights to drive with them off so it's never an issue for me. I always have the DRLs on in the day or lows at night. I just found the hypeflash by accident.

If I had to buy the headlights and harness with this in mind I would do it again in a hearbeat! Just mentioned it to puppypunter as he wanted feedback.
