Alpha Rex TRD Pro Style - DRL Problems

I recently installed the Alpha Rex TRD Pro style headlights and love them but have one problem with them. When I turn my DRL’s on, they don’t turn on. When I turn my headlights on, the headlight finally turns on. I see this is a common problem with them but I don’t know how to fix it. Maybe it’s a bad wire harness I received?? The wire harness has the box that makes the lights dance…. Can anyone help?

 

what year model truck / headlights?

 

It’s a 2020 TRD sport. I didn’t use the add a fuse.

 

You need to use the add-a-fuse connection to the ignition fuse in the fuse box. That tells the box to turn on the DRLs.
