Oem led headlight swap DRL not working

Hello,

I recently installed 2018+ oem Led Headlights onto my 2017 sr5 tundra with the headlight revolution harness. Everything seemed to be going well but I can't seem to get my DRL's working. I've swapped the black/white and purple pin to resolve the blinker issue but can't seem to find why my DRLs aren't working. Posting here hoping to look for a solution.

Thank you

 

I had the same issue with the same setup except I'm a 2014. Traced it down to a wiring harness that was loose. It's a connection point that has two wires going into one. I wiggled the wires starting at the headlights and found it quickly. MY fix was to fid a position that it worked in and duct tape it to the sidewall. Has been working since. I will try and take a photo when I get home.

I would suggest start wiggling wires starting at your headlights and work towards the fuse box. See if anything gets it to work. Also I would check the fuse in the box and make sure that is in tightly as it takes up more space and can come loose.

 

Cant help with the headlight revolution harness, or why you would need to swap pins to make it work.

But I do know the @iHacker harness is top quality and works without issues, mods or pin swaps.
