Your will need to remove your headlights from the car. If you have not done this before you can follow this DIY:

After you have the headlights out you can mount the demon eye LED. The demon eye LEDs needs to go anywhere that shines into the Bi-xenons lense. I found a way to mount it (thanks @chappin) without breaking into the headlight cluster and taking everything apart.

If you open this side light cover (ignore the resistors):



You will be able to mount the demon eye to this location:



Video reference to find this mounting spot:

I tried to screw it down, but didn't have a small enough drill bit to make a guide hole, tried with a self tapping screw also, but that plastic is very tough and didn't want to risk breaking something. So I used heavy duty double sided tape as seen here:



Then secure it down to the mounting spot:

Then cut/file a small rectangular chunk out of the cover to allow the braided wire to run out of the headlight:



Then put your headlights and bumper back on. Route the braided wire to your wifi/Bluetooth/RF controller that comes with most demon eyes, then to the power source. I used the car battery for the power for the time being, will be wiring it up to a 'add-a-line' fuse tap soon.

This is where I tucked the braided wire from the headlights to the battery and you can't even see the wire once tucked correctly:

Then your done :)
