Relay Wiring for DIY LED Daytime Running Lights (DRL)

I'm going to be replacing the bulbs with the brightest/white 194's LED that I can find to make them more visible in daytime.

I've searched the forums but had difficulties finding the info... Do you have a link where I can find the hatchback headlights wiring diagram so I can splice the hi/lo signal source to the relay?

thanks!

I didn't know that the sedan and hatch shared almost the same wiring. I went and checked the same fusebox and managed to splice the same wires to make the bulbs I wanted to use as DRLs work (i.e. parking/city lights inside headlights).

There's a slight difference though compared to which BAT wire zuberio used. I ended up tapping the brown wire (85) since it's the only one that switched LO (86) to 12V to energize the relay coil whenever I switched the headlights on.

Now I have my DRLs back! Now I just need to find the brightest LEDs to swap the bulbs with.

Well, the LED swap didn't make the lighting any brighter so I added a pair of dedicated DRLs and mounted them between the lower grill.

This pretty much concludes my quest for DRL (for now, haha).

That just looks awesome, a job well done! I need to do that for mine too, only I have no idea. Probably really pricey to have someone else to do it for me...
