2025 Turn signal wiring?

I have a 2025 platinum tundra. I added new vent lights to the front grill. The white lights are wired switched from the key. My question is the new headlights seem to be all LED Including the turn signal light. There is a gang connector at the headlight. I was wondering, which wire controls the turn signal? I am worried that it might be pulse with modulated. Looking for a schematic and recommendation for which wire to tap into? I do not want to create damage to a module if it’s controlled that way.

 

Everything is led and is all controlled through the ecu. These trucks are sensitive to any kind of voltage variances with anything running through the ecu. Why do you need to tap into the turn signals though?

First off, I agree with @Danman34 the Gen 3s are sensitive to electrical variances, not sure about the turn signal circuit.
Assuming your platinum has LED headlights, he is also right about your platinum having a headlight ECU which IMO would make it even more sensitive..

Proceed at your own risk..


That stated the connectors are A53 and A54
Pin 11 hot for the turn signal
Pin 12 is ground




It looks like the front and rear turn signals have different feeds from the combination meter flash circut.
Perhaps tapping into the rear turn signals would be less of a risk than tapping into the front LED assemblies.



Good luck..

I have seen several 3rd gen guys add these lights successfully.
Good luck!

 

Thank You! This is a great response and glad to see professional replies!! I added LED front Vent Lights. White light when vehicle is running. ( B+ switched) Amber flash when turn signal is activated. Red wire is for running light. Yellow wire is for amber turn signal flash. This connection to be made to Turn signal lamp.
I am retired wrench and understand electrical load/controls. Just worried what strategy is used to activate the turn signal.

 

You can try tapping into the turn signal feed in the A53 / A54 connectors as described above.
But there are a couple ECUs in that circuit.

If you had halogen headlights it would be ano brainer, but the LED headlights are a bit more technical.

Did you find your DRL feed for the white DRLs?

 

I tapped into the driver side power distribution box. There was a terminal that is switched B plus. I’ll have to take a picture of it later
