You can find the pin numbers on the inside of the clip (the side were
the wires come out) i will post part number for the head light clip on
monday (have to call the body shop)



The colors match up with the older x5s except for the parking light and
turn signal they are all in one wire, so what i did is take the parking
light wire



GR/GN left side 01-03 and conect it to the pin #1-BL/GN on the 04/05 left side



GR/BL right side 01-03 and conect it to the pin #1-BL/BR on the 04/05 right side



then for the angel eyes i taped into the Xenon wire, but then they only
turn on when u have the Xenons on, i first tried it with the parking
light but the problem that i had is that when u signal your angel eyes
on the side that u are signaling form will blink too.
