Which wire is for the DRLs?

What the title says. In reference to the headlight wiring harness, in a 5th gen. 2020 if that makes any difference. Cannot find a straight answer anywhere, not even in the schematic diagrams.

 

Isn’t DRL just the high beams at a lower voltage ?

 

Originally thought so, but thats not it.

Trying to wire some lights so they come on when the DRLs are switched on in the cabin. We originally tapped into the high beam wire, under the same impression, but the lights came on when the high beams were switched on, not the DRLs. So the DRLs must be something else...

 

the high beams use some type of pcm. So unless you can decode the pcm, the power driving the drl can’t be used.
