Dear all,

I failed my first attempt to install the HID kit today as i couldn't local the 12V terminal for the relay harness. I saw a post before I need to pop open something near the bottom of the fuse box. I found a black cap near the bottom left of the fuse box but couldn't put it. Is this where the 12V terminal is? If so, can some guy me to open the cap?


Thanks.

I would very much appreciate if someone wrote a small description and added pictures on how to get 12V from the fuse box and upto the top of the dashboard.

Don't want to experiment to much with my new car and setting of all the airbags at the same time :D

Yes, still have problem locating the 12V post inside the fuse box. I see the 12v terminal for jump starting the car, but read there should be another 12V post for better usage on hooking up the reply harness for HID kit.

Appreciate any help.

Thanks. I went to look for it again after posting and finally found it under the Black trapezoid looking cover. Used two small flat head screw driver to unlock the two clips to open it. Hooked everything up including the relay harness, the HID KIT works like a charm.

Thanks for the feedbacks.

You don't need the relay harness for this car. Don't worry about trying to pull 12v directly from the battery.
If you read all the posts related to HID install we still haven't resolved the misfiring problem for installs without the relay harness.

And we still haven't confirmed installing the harness fixes the misfire problem.

LOL audi4t.

Here are the pix, sorry but i didn't have time to take off the cover. But you can't see any cables even if I did as most of the wiring are under the metal frame of the car. Everything is cable tied to the frame as well.

thomasnsx: do you have the misfire problem with the HID kit and the wire harness. I have the harness connected the same way and having the misfire problem. Where did you ground it to?
So far so good, it's only been a few days as you can tell.
I grounded the relay harness ground to the metal frame near front bottom left.

I'll try to find time take more pictures.


Personally, I'm not sure if the misfiring issue is really just the brand of ballast/bulb is used. I have my fair share of cheap HID kits in the past, but I always get good ballast. The only problem I have in the past are cheap bulbs burning out after 2-3 years. But before it burns out completely, it will "misfire" for months before it eventually don't fire up at all (burnt).

If you could try this method and see if it misfires it would greatly be appreciated. If you have a garage park your car in the garage. Turn the lights off. Do not have it set on auto. Then start the car and let it sit there for 20 seconds or so. Them turn the headlight stalk to auto and see if both fire up. Almost all the time both of my ballast do not fire up. I have checked all my connections several time and I have the relay harness and still running into this problem.

Thomasnx,

You actually open the fuse box easier by pressing a tab in on the front and lifting. :D




By they way you lights look great, you HIDs match the color of your DRLs; hope your misfire problem goes away.

I really like the color of my lights at 6000k, but I wonder if i should have gone with 5000k or maybe even 4500k, becuase the 6000K are so white that the DRLs looks a little yellow and my Sylvania Utra whites look even more yellowish (LOL , I have been leaving them off)

the problem i have is after driving my car to the garage (during daytime) and the switch was set on auto, let it sit for like 20-30 second, then the light automatic turn on, the driver side never fire up

That method works also. Do you have the wire harness installed? I have it installed and still running into this problem. I just want to make sure I am not the only one that still has this problem even with the wire harness.
