It would appear that the wiring harness for the GEN2 Predator Chromium V2 is a little different. The following still holds true:
Angel Eyes Wiring Example - 2000-2003 X5
Except replace brown with yellow and pink with white. There are no ballasts for the model I have. I did have to switch the bullet wires (red/black plugs into brown/white) from side to side once since the wiring is side specifc.
I chose a different location to mount the relay & ground:
The cover for the engine wiring harness was a bitch to get off. But once off it's easy to splice into the ECU wire and solder it together. There is a rubber grommet on the right side of the plastic box you can pierce to run your wire through. I also pierced the rubber grommet on the left side of the weather stripping near the hydraulic hood support and ran it under the rear engine bay weather stripping as suggested in the article above.
The rings lit right up when i put the key in the ignition and turn to postion 2. They are pretty damn bright! They stay on for a couple seconds after removing the key. Works for me :-)
Now I just need to pull headlight assemblies out. I figure while they are off the car before I bake 'em I will burn off the haze with some wax and my Porter Cable random orbital buffer.
I'm going to break the orange waffles out and go clear. I have amber SMD LED bulbs to replace the stock ones with along with the capacitors to prevent the bulb out OBD2 message. Hopefully I can fix my turn signal switch issue at the same time.
