Hi
My G35C is from Asia and I see some differences in lighting.

the side marker only blinks when I turn signal light.

I want to make it always turned on when I turn the light on. (this seems normal in american ver.) and also want it to blink when I turn signal light.

I went to the local shop and they charge me too much for this...50 bucks...lol

please let me know how to make this work. I want DIY...

 

It would help if we knew what year it is...
