2018 Tundra LED headlight wiring info with diagrams

Nope, on the signal adapters I made, the wire positions have already been switched around. For you it will be plug and play

 

@thomasbus337 thank you. I am so lost on the DRL portion of this setup. Is there any way you could make the DRL setup? I can pay you up front for parts and labor. I have the moto module I just don't know how to make the rest for the DRLs to work on a Pro

 

@eledobleu can you please make me the LED DRL relay for my 17 Pro. I got the LED headlight harness from thomasbus337 but I am lost on how to make the LED DRL portion. Can I please order one or however you want to do it? I already have the moto control

 

Once parts arrive, I will make the harness for you.

 

Let us know!!

 

I will see if it's possible to upgrade the wiring in the motocontrol to 16 gauge wire maybe is doable just wondering about that.

 

I looked at it on mine and I don't believe it's possible. They have the two 20awg wires twisted together and crimped on one small terminal on the plug that enters the gold relay. I doubt we'd be able to squeeze two 16awg wires together on that small of a pin.

 

@eledobleu thank you very much! Let me know if you need any other info from me

 

I'm getting my headlights this coming Monday to start making my harness, I'm still waiting for a few connectors to complete my harness

 

Can you please add me to the list as well for my 2016 Limited CM. I have the harness from Thomas, but as others lost on the DRL portion. Also, I have the motocontrol as well.

Thanks!

 

Yep, me too!

 

If you want to get on the list, please email me at eledobleuretrofits@gmail.com

 

@eledobleu I will also add my info to the email you provided for this

 

Hey guys how do you unlock the white connector to insert the new terminals?

 

Grab a small screwdriver and pry around the inside seam. The center section pops off the front. All of the Toyota connectors I have worked on for this project unlock from the front

 

Use a small screw driver or pick. Pull the highlighted area out and it will come out.

 

Hey guys!! I am having trouble here. No high or low beams, and DRLS aren't working. Turn signals and amber DRL work fine. @thomasbus337 @BlueBottle anyone have any ideas? Truck is a 1794.

 

Your pins in the eight pin connector and on the DRL 4 pin connectors are reversed

 

Yup. That white connector needs to be rotated 180degrees.

 

Don't pay any attention to my wire colors (this pic was taken from my first harness prototype) but with the squeeze tab is on the bottom of the plug you want the row right above the tab to be the Hi/Lo and ground and the top row is the LED DRL[GALLER

Also, the red DRL wire needs to be in pin 1 and the violet is in pin 2

 

OK thank you so so much for the quick response. I have corrected the white harness. My headlight functions perfectly now. The only thing it's not doing is dimming the white DRLS, which I preferred them to be on full brightness anyways. Would swapping the red and the purple on the black harness cause the DRL to Dim? Or have I found a weird way to keep it from Dimming without disconnecting the purple wire from the black harness

EDIT: I've swapped the red and purple wires on the black harness and the white DRL stays dim constantly, whether headlights are on or not. If I switch them back to how o originally had them, they remain bright all the time and don't dim.

 

Thank you so much for all your help bro, you guys have been so awesome and helpful. I really, really appreciate the time you guys are taking to help me. Thank you so much !!!!!

 

I'd double check that you have the red and violet wires in the correct spots and maybe even check the DRL fuse under the hood. Something might have blown when you had the wires crossed

 

Would the wiring staying in this manner (red and purple reversed) cause any harm if it already blew the fuse? It's functioning as I originally wanted it to (DRLS on high all the time). Do you know which fuse is the DRL one by any chance? Thanks for all the help @thomasbus337

 

The fuse will be labeled LED DRL and is marked under the lid of the fuse box. I'd be afraid that having the LED strips on full brightness at night might make the Amber directionals less visible

 

Anyone have a photo of all the plugs/lights into the back of the headlights? I see that the 8-pin goes into the back of it and the "park light" needs to be reconfigured per instructions on page 2 of this thread. What I am wanting to know/see is does all the other plug/lights remain the same with no re-wiring or re-configuring?

Also @thomasbus337 did you get the messages I sent? Will my diagram work?

 

I had the same issue. look at the respnsonses i got. all hi low should be connected to negative. I had to switch my wires and it worked perfectly

 

Thanks so much Steve!!

Did you ever figure out what to do with the brown connector on the passenger side?? The drivers side is the only one with one apparently, I can't find a place to plug it in on the passenger side. Did you just electrical tape it to cover it? @thomasbus337 @BlueBottle

 

Take it well to one of the wire looms. Make sure it doesn't contact anything or you will blow a fuse.

 

Thank you so much for the fast response, you guys are so awesome !!!!!!!!
