Angel Eyes Wiring for 2000-2003 X5's
 

The pic below is the wire/relay harness from the Predator chromiums and I numbered each connection with a corresponding description/where to connect info.

KEY:

1. Relay - to be mounted close to the power supply djbock's pic

2. Fuse-last item to be installed, so remove from socket first

3. Power Supply- connect to positive terminal of battery (engine bay)see pic

4. Ground - i mounted mine where the hood's ground connection is clik pic

5. Brown wire - goes through the fire wall into the footwell light, connect to the blue/red strip color wire of the light assembly connection, Just to elaborate, the footwell connection is so your new eyes illuminate when you hit the remote button open, lock or even to open the trunk.

6. Connect to ballast#1 see pic there are different wire color sets for the ballasts/harness for this, so i just did trial and error!( ex. if A to A and B to B dont work, then it should work A to B and A to B) and success was achieved

7. pink wire- connect to ECU ( look for white/red strip color wire) so AE on when key position is "on" ..pic 1 .. pic 2 .....i just found out that the wiring will be different from the 3.0 and 4.4, ( the red/white strip wire is the third wire from the left on the black socket connector for the 4.4-see pic) ( for the 3.0, it is located differently-i think its on the 2nd row--so just look for it)

8. connect to ballast #2 ...see pic

For X5's with PDC: this article is for you: http://www.jlevisw.com/CWP.pdf

Looks like this if I'm correct.

#4 is a ground
#5 goes to the foot well
#7 goes to the ECU which is just a power on switch when the key is in the #2 position.

Yes you connect the ballast to the wire shown. You will need wire connectors (best to use a removable connector) and make sure Brown goes to Brown and Red to Red.

How is that...And I've not installed mine yet.

Just to elaborate. The footwell connection is so your new eyes illuminate when you hit the remote button upon entry. The ECU you will need to look for a 12V power on when the key is turned to the on position. Any 12V should do that is switched.

Hope that helps.

I've been doing my homework.

I put different connectors on the ballast wires to connect to the harness.

updated... pic added ( ground connection for hood )

go to radioshack and buy some bullet connectors...weld those on to the wires :)
