DRL wire for lighted T?

[y2kcurt]

I am trying to find the correct wire on the headlamp assembly to connect the front lighted T so they come on when DRLs are on on a 2015 Model S. The instructions say to connect to the red wire with white stripe for headlight power or the orange wire with black stripe for DRL power. I cannot find either of these colored wires on the headlamp assembly wires; see picture.

Anyone know the correct color wire to choose?

Thanks

Tesla changes the wire colors so it's hard to know. I suggest you get a 12v tester like this one and test each of the wires until you find the right one.
