I'm posting this from Japan.
Sorry for not proper English.

Dose anyone know about headlight connect wiring?
I just looking for DRL(may be, same as positioning light) line.
Because My DiscoV MY2018 DLR(No AFS) dose not woking in Japan. It woks as only positioning light.
And positioning light brightness is not 100%.
So I built DRL control unit using relay.
It supply 12V from battery directly when EG ON and Head Light and Direction Indicator are OFF.
But I can not indentify DRL(or position) line on head litght connector.

I checked voltage of each line.

A number of pins on headlight side connector is seven.
(Please refer to picture for positions of right side connector and headlight pins)





All OFF(Acc OFF, All Light Off)
Yellow/Violet:0.7v
Violet/Orange:0.02v
Green/White:12.27v
Blue/Green:0.02v
Chacole/Yellow:6.98v

Acc OFF,Position ON
Yellow/Violet:0.71v
Violet/Orange:0.02v
Green/White:12.09v
Blue/Green:0.06v
Chacole/Yellow:7.08v

I expected the voltage of some line will be different in position light ON/OFF.
But looks like same voltage.

I identified lines not DRL(position) by testing other test pattern.
Yellow/Violet: Direction Indicator
Violet/Orange: Low Beam
Green/White: ??
Blue/Green: Flap(High Beam)
Chacole/Yellow:??

I suspecting Green/White or Charcoal/Yellow might be DRL(and position).
But those line has voltage no matter wether position ON or OFF.

Does DRL Sigunature LED might be PWM(Pulse Width Modulation) controlled on/off/brightness?
If so, I'll try to direct connect 12v to position light line from battery , but I don't know which is position/DRL line.

Please some one help me.

Thank you.
