As I've said before you can't, unless you open it up and tap the pcb. Theres a reason why the JDM only has 6 wires, USDM has 6 wires and the EUDM has 7 wires. JDM taps only the low power configuration (Night Light), USDM taps only the high power configuration (Daytime Light), EUDM taps both Low and High (Hence the 7th wire as EUDM has Daytime lights and Nighttime lights). You could probably also have a resistor to lower the power going for an option for not opening the headlights, but its a DIY project. I've owned both JDM and USDM OEM headlights and I've seen someone here with a DIY on EUDM lights.
The easiest solution without doing any work and blinding people would be buying EUDM, but EUDM has no DOT stamp on it.

This is a good writeup on the wires and how they function. The wires im referencing to are the White and Green wires. The Green is LED LOW and White is LED HIGH. JDM uses the Green only so not DRL. USDM uses the White only so no Nighttime light. EUDM has both.
TLDR: Repinning will do nothing, you need to tap the LED LOW on the PCB or put a resistor on the LED HIGH Wire.
