Hehehe, no worries, it doesn't matter, I used double sided tape to secure the board to the case...
Anyhow, I finished the Halo's today. They work as intended and look awesome. Here are some pictures:
Right headlight (looking from the car inside). The connector is shown in this picture and I have drawn 3 letters:
K - Low beam (dipped beam, passing beam, meeting beam)
D - High beam (main beam, driving beam, full beam)
M - Indicator (turn signal)
The wire that is needed to be soldered to is above letter.
From the bottom up:
blue with red stripe - indicators (this wire is just stripped, still not soldered)
gray with red stripe - high beam (this wire is stripped and soldered)
green with white stripe - low beam (this wire is stripped, soldered and isolated)
This picture is for left side headlight (drivers headlight in Serbia)
Here is almost everything soldered, stripped and isolated. The yellow-green wire is for sidelight, I connected the turn on signal for the halo controllers to this wire, so when I turn on sidelights, the halo turn on, when I turn off the sidelights, the halo's wait about 10sec than turn off...
If someone needs some more explanation, I'm happy to help. It's all the same as on wiki page, with the difference of starting the rings. My rings start from the inside to the outer, firs light up High Beam, than indicators, than low beam rings. Here is the video:
